Recruitment is extremely important and impactful. Some people should be completely obsessed with it.

Cross-post from Good Structures.
Over the last few years, I helped run several dozen hiring rounds for around 15 high-impact organizations. I've also spent the last few months talking with organizations about their recruitment. I've noticed three recurring themes:
Candidates generally have a terrible time
Work tests are often unpleasant (and the best candidates have to complete many of them), there are hundreds or thousands of candidates for each role, and generally, people can't get the jobs they’ve been told are the best path to impact.
Organizations are often somewhat to moderately unhappy with their candidate pools
Organizations really struggle to find the talent they want, despite the number of candidates who apply.
Organizations can't find or retain the recruiting talent they want
It's extremely hard to find people to do recruitment in this space. Talented recruiters rarely want to stay in their roles.
I think the first two points need more discussion, but I haven't seen much discussion about the last. I think this is a major issue: recruitment is probably the most important function for a growing organization, and a skilled recruiter has a fairly large counterfactual impact for the organization they support. So why is it so hard for organizations to hire them?
Recruitment is high leverage and high impact
The majority of an organization's impact flows through its recruitment function. Since most organizations in the high-impact charity sector are research and advocacy organizations, most of their impact is a direct function of the strength of their talent. I think that choosing who to hire is basically the second most consequential decision an organization makes for its overall impact (after choosing what to work on), and importantly, it's a decision organizations are often willing to have early-career or more junior staff be involved in.
Additionally, basically all other consequential factors in an organization's impact are downstream of recruitment:
- Is your strategy strong? It probably depends on hiring people who think well about strategy.
- Is your culture good? It probably depends on hiring strong managers.
- Is your organizational structure effective? It probably depends on hiring the right people for the right roles.
If a recruiter is directly involved in the assessment of candidates, they directly generate value for the organization based on the strength of their choices and assessments. But even recruiters who don't directly evaluate candidates generate large amounts of value. They might screen initial candidates or help design assessments while a hiring manager makes advancement decisions. That is still a major factor in shaping the outcome of a hiring process.
And recruiters also reduce the time cost of hiring. Hiring is incredibly expensive for organizations. I'll typically spend 50-60 hours in a given hiring process for a direct report, and expect a similar amount in total is spent by other people involved. If I run an organization hiring even a few roles per year, it's easy to see the costs of hiring adding up. Recruiters can directly help reduce this burden, both through their work and through process improvements like designing more effective evaluations.
Organizations struggle to hire recruiters
Among hiring rounds I've run for organizations, two types of rounds have consistently failed to find strong candidates: leadership roles and recruiting roles. Leadership roles are understandable, as these hires are obviously very consequential for organizations, and there might be very few people who are a good fit.
My impression is that there is a gap, both in candidate pools and in service providers, of highly aligned, competent recruiting talent. When I've run hiring rounds for recruitment roles, organizations have been unhappy with the talent pool and often failed to make successful hires.
Why do organizations feel so unhappy with their recruitment talent pools? I think a major reason is that doing recruiting well, and especially managing a recruiting function, requires three core competencies:
Project management
Recruiters have to manage thousands of applications, handle individual emails to hundreds of people, and generally execute big, complex project management tasks. This is genuinely difficult and doing it well requires being thoughtful about communications, highly organized, and able to process large amounts of information quickly.
Decision-making under uncertainty
Hiring is inherently extremely uncertain. Our best selection methods aren't that good, and organizations that hire according to theoretically optimal selection methods still regularly face performance issues in their staff that they shouldn't expect if hiring perfectly predicted skills. And hiring is rife with uncertainty beyond "are you choosing the right person?":
- Did you scope the role well? Is the role you scoped actually going to work the way you expect?
- Was your candidate pool competitive? Maybe the salary was too low or maybe you didn't reach the right audience. You don't know who didn't apply, so it's hard to directly assess whether you're scoping the role and process well.
- Is anyone in the world actually a good fit for this role? The shorter the list of people who are actually qualified, the worse you should expect your candidate pool to be.
Ultimately, doing recruitment well is about successful project management, but it's also about building tools to make decisions under uncertainty, and then testing and improving these tools over time. Doing this requires research skills, data analysis skills, and other competencies that aren't usually considered part of the recruiter profile. The hiring tools organizations have tried (interviews, work tests, etc.) are pretty limited in the scheme of things. There is a ton of opportunity to try new methods for evaluating candidates, and for testing and improving those methods over time.
Understanding of the ecosystem
For organizations in specific cause areas, recruiters who understand their ecosystem can make a major difference. It's unclear to me if this is a good thing, but in reality, organizations rely heavily on referrals from other organizations and signals about candidates' context and value alignment. Having recruiters who can see those signals and interpret them, or decide when they're worth ignoring, helps improve the evaluations organizations make of candidates.
For organizations, it might really matter, for example, that a recruiter recognizes that a background working on responsible scaling policy at Anthropic is meaningfully different from a background working at Pause AI, despite both presenting as organizations working to ensure that AI is developed safely. Or it might make a major difference to an animal welfare organization that a candidate came out of Direct Action Everywhere vs. Shrimp Welfare Project.
To be clear, I'm not convinced that using context clues like this is particularly wise for organizations to do (or at least, to use as a major point of assessment). But it is part of how groups approach recruitment, and having recruiters they can rely on to do the same is part of what they're looking for.
These three skills are very different: candidates need both the operational skills of doing project management well and the research and empirical skills of trying to make good decisions under uncertainty. Finding someone with both of these who also has context on the ecosystem is even harder. Organizations looking for all three routinely fail.
Many of the people applying to recruitment roles emphasize their experience in recruitment. This isn't the background organizations need
When hiring recruiters, usually the hiring pool is made up of many people who have a high degree of project management and operational skills. Candidates tend to be operationally focused and emphasize this part of their experience and background.
But often candidates won't have either the research/empirical skills to explore ideas to improve hiring or won't be interested in this aspect of it. And often organizations are looking for candidates with significantly higher context on the ecosystem they're in than the candidates have.
The differentiator for organizations in hiring recruiters seems to usually be someone having all of these skills, not just the operational ones. Finding people at that intersection is much harder.
Almost no one is appropriately obsessed with hiring
The hiring tools organizations have are really rudimentary. Basically, organizations have a brief scan of resumes, some answers to short-answer prompts, a few interviews, and a few hours sampling candidates' work. Even organizations with great recruiting practices routinely struggle with performance issues internally. And organizations I've spoken with have struggled to automate (or don't trust the automation of) large parts of their review, meaning hiring anyone requires dozens of hours of reviewing materials of candidates who won't be advanced. All of this suggests that there are major gains to be had from trying to improve hiring at organizations.
But my impression is that most organizations aren't focused on things like experimenting with their hiring, running tests to try to improve the impact of their approaches, evaluating candidates they rejected to see if they might have made mistakes, or otherwise doing the basic steps it might take to make hiring more effective.
Given the importance of hiring, this lack of obsession is surprising. Hiring successfully is a critical part of organizational impact, but barely any time is spent trying to deeply understand how to do it well.
High-impact organizations need people who are completely obsessed with hiring. By this, I mean people obsessed with answering a question like, "How do I attract the right pool of people to a role and identify the best candidates out of tens of thousands, in a way that is minimally onerous for both candidates and my organization?"
I think that there is a huge opportunity for people who are obsessed with these kinds of questions. Answering them well unlocks a huge amount of impact for organizations, and we genuinely don't have answers for them.
The state of evidence on hiring practices is bad
A lot of the reason that organizations struggle with hiring is that the evidence base for how to assess people is terrible.
There isn't a (cheap) way to run true RCTs on hiring and evaluating hiring rounds often faces a fundamental statistical issue: in progressive rounds, you eliminate the people who did poorly in your assessment. But doing well in a hiring round is a separate skill from doing well in a job, so you're inherently filtering on a different skill set, to some extent, than the one you want to measure. So you will never get information on the relative performance of people you rejected and be able to make confident claims about the predictiveness of your hiring.
That being said, we can still collect some evidence from hiring rounds: industrial/organizational psychologists have tried to study what hiring methods are most predictive of later performance. While all these assessments suffer the issues outlined above, we can still glean something from them. But unfortunately, the evidence they produce is mixed at best:
- The best methods of assessing candidates are at best only moderately correlated with later job performance. While presumably you can improve this by assessing candidates using multiple methods, if you believe, like I do, that the distribution of talent is extremely right-tailed, then moderate correlations just aren't going to be particularly useful for finding the most talented people. You can do a good job eliminating candidates who aren't a great fit, but if talent follows a right-tailed distribution, confidently determining who the best candidate is is much more important and much harder.
- The field suffers from the statistical issues of all psychology. For example, for years, general mental aptitude (GMA) has been thought to be highly correlated with job performance. Then, in 2021, some researchers claimed that a major study underpinning this claim had (in their view) made some dubious statistical choices which, when corrected, led to GMA being a much worse indicator of job performance. Without weighing in on the debate, that it is a major debate indicates that these questions are not settled even among the researchers who have spent their lives studying them.
Separately from choosing the right evaluation method, organizations have to design the evaluation well. If I am hiring for a software engineer and have them swim a mile for their work test, I'm fundamentally not testing the right skills for the job. Recruiters have to answer difficult questions like:
- How do I even figure out what the right skills for a job are?
- What do I do when these skills are in conflict with other things I care about? Many of the highest-performing people I know work really long hours. Is "working really long hours" actually a skill I want to filter on? Or is it one of many potential proxies for something else that matters more?
Retaining strong recruiters is really hard
Many of the people who are best at recruiting and convincing talented people to join their organizations aren't in recruiting roles. Instead, they are in leadership or research roles. And it often seems like convincing someone to stay in a recruiting role, especially if they have research skills, is difficult. But this seems like a mistake — finding recruiters with the data analysis skills, research literacy, and operational skills to run experiments, improve systems, project-manage hiring rounds, and overall make the recruitment experience positive for candidates is really difficult.
Organizations do sometimes find these people. However, many of the best recruiters don't stay in these positions for long. Instead, they often move into management, leadership, or research roles. This exacerbates the issue: many of the people with the most experience in running effective recruitment don't actually work in recruitment. The skills that make someone excellent at recruitment might also make them an excellent researcher or excellent project manager. And because recruiting isn't seen as particularly high status, people doing incredibly impactful work often move out of it to other roles.
I'm not sure what to do about this, but currently, my best guess is that recruiting should be viewed as having significantly higher impact than most people think it has, so there is greater social reward for staying in these roles.
Why might this be less important than I think?
High-impact organizations are usually pretty good at hiring, so finding better recruiters doesn't make that much of a difference
I think that most high-impact organizations are doing very reasonable things in their hiring: they're running multiple kinds of assessments (e.g., work tests, structured and unstructured interviews, work trials, etc.). Relative to other nonprofits, most organizations I work with in EA, AI governance, etc., are doing a good job at hiring.
If organizations are pretty good at hiring well, maybe there isn't that much to be gained from hiring a recruiter, or recruiting talent would have the greatest counterfactual impact by going to organizations with the worst recruiting practices.
I suspect this is wrong though. I have rarely seen organizations do things I think are fundamental to successfully evaluating and improving their recruitment, like:
- Conducting job analyses
- Evaluating the later performance of candidates they rejected
- Backtesting their recruitment practices to see if they predicted later performance
This is too hard
I don't think that the issues with recruitment I describe here are limited to high-impact philanthropy. I suspect that major for-profits, who theoretically should have heavy incentives to find the best talent, also struggle with them.
This indicates to me that there are just hard problems in doing this well. We might only make marginal improvements from the current best approaches.
I find this pretty convincing and think it's possible I'll look back at this post in 10 years and think it was misguided.
But again, I've not seen anyone try to just take recruitment as seriously as I think it deserves to be taken. I think given the stakes, it deserves a shot.
I'm trying to find people interested in this kind of approach to hiring. If this is you, please reach out.
This post isn't meant as a pitch, but I'm trying to find people who are interested in exploring roles in recruitment, who are obsessed with hiring, or are interested in taking a highly empirical/experimental approach to hiring. If this is you, get in touch! I'm both looking for candidates for my own work and am regularly asked for referrals for recruiting roles.

I agree with a lot of this post and I'm really glad you wrote it! I would be very excited to see readers with whom this post resonates apply for the Open Phil recruiting team (which I manage). I think our team's work is extremely high-impact and we've often found it hard to hire great people onto it in the past.
One place where I slightly disagree with the post is on the value of past recruiting experience. Most of our team had ~no previous recruiting experience before joining the team, and that hasn't stopped them being successful in the role, so it's very far from a requirement. However, it does mean that past recruiting experience can be a valuable differentiator for some candidates. At the risk of speaking too specifically to my past self, anyone who has a background in recruiting (in any context) and is interested enough in high-impact work to read this comment should know that their application would be extremely welcome!
NickLaing @ 2025-11-08T05:59 (+2)
thanks. how do you know the recruiters have been "successful". Open Phil would get lots of incredibly capable applicants for every job, how can you know the counterfactual effect vs. a more experienced recruiter?
Can you maybe describe why you think experience wasn't important for this job? I know EA orgs do value experience less than others....
"Most of our team had ~no previous recruiting experience before joining the team"
PhilZ @ 2025-11-08T13:02 (+1)
Thanks for the questions! By 'successful' I just mean something like 'our team is doing a good job of accomplishing its goals, and that's down to the great work of individual team members'. I think we do well at making the right counterfactual hires based on our attempts to identify what qualities we're looking for and to get signal on those qualities throughout our hiring process, but we can't know that for sure; that feels like a pretty fundamental limitation of hiring work to me.
Re: experience, I think many of the core skills required to be a successful recruiter are transferable from other kinds of roles, and we're happy to train new hires up on any gaps. Our job description highlights the kinds of skills I think are helpful, and I overall agree with Abraham's discussion of this topic in the original post too. That said, part of what I was trying to communicate in my first comment was that more recruiting experience would be helpful on our current margin (not speaking for any other orgs)!
As a heads up, I probably won't respond to further comments as I'm on leave for the next few weeks and don't intend to be on the Forum much.
Stien @ 2025-11-06T04:03 (+11)
I find this very interesting to think about. Your reasoning makes a lot of sense to me, and I agree that these practices would make organizations more impactful. But, being in the animal welfare space, these questions feel like fanciful thought experiments (until that Anthropic money comes in, or do we not talk about those dreams outloud?). I know you already know this, but Animal charities don’t have the resources to do rigorous testing of recruitment practices (or to offer competitive salaries). At ACE we can’t afford the time to systematically look at where rejected candidates end up or add prediction steps to the recruitment process—even though I’d really like to. I’ve seen the difference that excellence makes, but the hiring cost is already so time consuming that adding MEL would likely come at the cost of all the work necessary to retain that talent. We’re also too small to get much meaningful data from experiments.
But I could see how a centralized capacity building organization in the effective animal advocacy space could potentially play a role (Animal Advocacy Careers or maybe Sharpen Strategy or High Impact Professionals?). They could collect the data for job analyses, backtest, follow candidates, etc. across multiple organizations. That recruiter would need to thoroughly understand the theories of change for various interventions and organizations. They would also need to understand which competencies and attitudes fit those different contexts best.
Meanwhile, the charities must be willing to really engage humbly and transparently with this central recruiter and with other animal orgs. Can the EAA community look at the replaceability and counterfactual impact of the movement’s talent pool, without a competitive or scarcity mindset, and encourage their people to move so we collectively do the most good?
I would like to think about this more, but first I need to raise the money to make sure I can keep my current staff next year and hopefully provide them with COLA and maybe an extra 0.5 FTE in support. (No, not bitter about the lack of funding for animal welfare at all.)
Re: your three identified core competencies, project management is the one I would be most willing to compromise on in a recruiter, because you could potentially mitigate that skill gap with tools or admin assistance. But the ability to be a strategic sparring partner with the hiring manager seems non-negotiable. Same with a desire to test and improve hiring methods because they are determined to figure out the puzzle of getting people in places that sets the org up to do more. You need someone who questions decisions, not a go-fetch headhunter.
Anyway, I like this obsession with the meta recruiting of obsessive recruiters.
abrahamrowe @ 2025-11-07T16:30 (+4)
Yeah, I agree with all of this difficulty. But, I also think the animal movement trends too far in hiring too many people, and all things considered, I'd probably prefer an animal movement that was smaller and more strategic (though this is partially because I don't think ambitious animal welfare goals, like abolishing factory farming, are tractable), and think the things that are tractable (wild animal welfare policy, shrimp welfare, etc.) would do better if coordinated by fewer talented people rather than more mass movement — but I recognize that I'm the only animal advocate in the world who is against broad movement building so don't put too much stock in my views.
I also think the animal movement suffers from a lack of "coolness" unfortunately — e.g. I think AI risk, for example, just has more general appeal / trendiness, and so they can appeal to a way larger audience of potential applicants, which should in theory mean higher quality (just because more people are interested).
I agree that it could be centralized — I think the benefits outweigh the risks here, especially for heavily EA organizations.
Stien @ 2025-11-06T04:26 (+3)
One more thought: I think your points also apply to the recruitment of board members.
Jason Green-Lowe @ 2025-11-03T18:22 (+9)
Thanks for writing this up! I broadly agree with your points and I think it's an important topic. One factor that I see as pushing in the other direction is that many EA-affiliated orgs are small, new, and/or have uncertain futures. Investing in the design of a higher-quality recruitment process makes the most sense when you're confident that you'll get to reap the benefits of that process across many hires and many years.
If you have a six-month runway during which you plan to make one or two hires, it's less cost-effective to spend dozens of hours improving your general hiring process (as opposed to simply trying to make the right individual hires). It's also less feasible to gather statistically meaningful data by running experiments on your (tiny) number of top candidates; even if you're willing to invest massive resources, there just isn't enough data yet to support most types of experiments.
I enjoyed the challenge of recruiting for the EA-friendly organization I led (the Center for AI Policy), and I would be happy to consider full-time recruiting roles, but I wanted to point out these challenges. It's not just that people aren't aware of or interested in better recruiting; it's also that sometimes their organizations aren't large or permanent enough to justify large investments in recruiting skill.
abrahamrowe @ 2025-11-03T20:34 (+4)
I definitely agree with this challenge — I also wonder if this is part of the reason many of the people who I have found to be most thoughtful about recruiting in the field founded or ran small or new organizations — they had to recruit under different constraints (e.g. offering less job stability, less name recognition, etc), and had to be more creative to get talented people in.
Stien @ 2025-11-06T04:14 (+1)
Though I understand the challenge and have this experience (see my other comment) I do see three related cases where it might be even more critical for a start-up or uncertain initiative to hire (and fire) well.
First, hiring in some novel organizations in nascent cause areas might have an effect on the development of a whole field. If there are only a few players, making a wrong hire could change the reputation of the whole space and slow down or reverse progress for the cause. E.g. If you're in wild animal welfare and provide credibility through employment to someone using unscientific methods or who is vocal publicly about highly controversial solutions to wild animal suffering, that could be disastrous for the development of wild animal welfare science. I could see similar risks in EA community building.
Conversely, if you hire the best, it could become easier to attract more high talent, accelerating the path to impact.
Second, in interventions where the reward of success is enormous but the risk of no or negative impact large, it seems critical to hire the best you can get.
And third, if you’re starting an org that’s trying something new, and you hire someone with average expertise, skills, or drive, or there’s a mismatch between competencies needed and offered, your endeavor might fail. This might lead you, and outsiders, to incorrectly believe the whole intervention isn’t tractable.
But, if you have short timelines and just need warm bodies who can be easily replaced, I'd likely also invest less in recruitment.
But yeah, I mostly relate to the frustrations of the impossibility of doing some of these ideal recruitment practices.
Kale Ridsdale @ 2025-11-06T08:49 (+6)
Thanks for writing this post, Abraham! I agree that recruiting is a very important and high leverage function that is currently undervalued as a career path by job seekers. I started managing the (new) recruiting function at CEA earlier this year but only after being directly invited to apply for the role; I very likely would have overlooked the opportunity and I think this would have been a mistake - which makes me worried others will do the same.
CEA is in a high-growth period and I think there's much opportunity to experiment with finding more effective recruiting strategies -- right now we're adding capacity to our Recruiting team which will allow us to keep up with our hiring needs while adding some flexibility to think strategically about our approach to finding talent.
I'd likewise like to hear from anyone motivated to explore their fit for recruiting after reading this post. I'm keen to find a very organized person who broadly understands the EA ecosystem, and while past recruiting experience would be a bonus, I don't think it's necessary.
SiobhanBall @ 2025-11-05T07:32 (+3)
I really appreciate this post. From being on the candidate side recently, and from hiring in smaller org settings, I’ve seen a lot of friction come from a reluctance to say out loud what excellence actually looks like for a given role.
When teams try to keep the funnel broad, they get hundreds of earnest applicants who were never going to be close to the bar. Candidates lose time, the signal gets lost, and everyone feels worse. Clear expectations up front, even if they narrow the pool, make the whole thing more honest and efficient.
I agree completely on treating hiring as a living system. We iterate everywhere else in EA, yet hiring often stays fixed and opaque. There’s a lot of benefit to experimenting, testing assumptions, sharing what works, and building more transparent models over time.
I’m very interested in this problem, especially approaches that combine clear bar-setting, structured evaluation, and genuine care for candidates. If you’re exploring ideas here, happy to chat.
abrahamrowe @ 2025-11-07T16:34 (+2)
Yep, I agree. I think a really good challenge organizations could work on is trying to get fewer applicants (without losing the best ones), because it just seems better for both candidates and organizations (candidates are more likely to get a role, orgs have fewer people to sort through).
Saramago @ 2025-11-07T17:27 (+2)
I wanted to share my perspective as someone you personally reached out to about applying for a role. I invested several days in the process, preparing thoroughly and rearranging significant parts of my life, including obligations to my children, family and day job, because I was genuinely excited by the opportunity and your encouragement.
After being told I was a strong, referred candidate, I received an automated rejection email less than 48 hours after submitting my application. While I understand that rejection can be an inevitable part of the process, I found it extremely disappointing that my follow-up request for any feedback or context went unanswered. I reached out to you 3 times.
For candidates investing substantial time and hope, a lack of basic communication and transparency is discouraging, especially in a sector that values impact and integrity. I hope you’ll consider your own role into recruitment processes and candidate experiences can be improved going forward.
abrahamrowe @ 2025-11-08T03:12 (+2)
Thanks for the feedback! I definitely think that the EA hiring process for job seekers is terrible. Doing multiple work tests, long applications, etc is awful. I'd be especially excited to get rid of written prompts in job applications (which I think might be possible), and work tests (much harder). And I'm sorry that experience was so negative — I invite many people who look like strong fits on paper to apply for roles, and in most hiring rounds I work on, candidates are evaluated blindly, so it's hard to perfectly tie these things together.
I couldn't find your specific case, but if you bump the email, I'm happy to tell you why I didn't provide feedback. In almost every case, it's because I don't think I have useful feedback to give people — I'm highly skeptical of most hiring evaluation methods, and think after reviewing someone's application, I, at best, have only the very mildest sense of their skills. I also have found that the only useful advice I have for people looking for roles in EA organizations is advice on how to game hiring processes, so generally avoid doing so.

Executive summary: The author argues that recruitment is one of the highest-leverage functions in high-impact organizations, yet it is widely neglected and undervalued; they call for more people to become deeply focused—“obsessed”—with improving hiring through empirical, experimental approaches, as this could unlock substantial organizational impact.
Key points:
- Despite huge candidate pools, hiring processes in the high-impact sector leave both candidates and organizations dissatisfied—suggesting deep inefficiencies in how recruitment is done.
- Recruitment shapes nearly every dimension of organizational success (strategy, culture, structure), making it second only to cause selection in determining impact.
- Organizations struggle to find strong recruiters because the role demands an unusual blend of project management, decision-making under uncertainty, and contextual understanding of the ecosystem—skills rarely found together.
- The current evidence base for hiring effectiveness is weak: even the best assessment methods only moderately predict job performance, and the field lacks good data or robust experimental validation.
- Many skilled recruiters move into higher-status roles, creating a retention problem and depriving organizations of experienced hiring talent.
- The author urges greater social and intellectual investment in recruitment—treating it as an experimental science of impact rather than an administrative function—and invites others similarly passionate about hiring innovation to collaborate.

Really insightful and tallies with my experiences. I would also add in challenges from broken processes indicating lack of organisational value placed on the function. E.g. receiving no responses from applications only to find out roles have been filled after repeated chasing; advised timeframes being massively missed; total absence of response from direct queries.
I wrote some thoughts from my experiences here, which might be added into the mix. Keen to help improve this vital function.
