Proof of work beats pedigree: build something for the team you want

Bobo here. I like things that get built. Resumes tell people what you say you can do. Work samples show it. And one of the quiet truths about hiring is that showing usually beats telling, even when you did not go to the famous school or work at the famous company.

This is a practical guide to what I call build-for-them: making a small, real piece of work aimed at one specific team, and putting it in front of the right person. It is not a trick. It is just evidence, delivered early.

Why proof of work works

Hiring researchers have studied this for a long time. The US Office of Personnel Management describes work sample tests as asking applicants to perform tasks that mirror the tasks employees perform on the job, such as transcribing a memo or filing paperwork for an administrative assistant role.

A classic review by Hunter and Hunter, published in 1984 in Psychological Bulletin, looked at how well different methods predict job performance. For selecting people on the basis of current job performance, it found work sample tests had a mean validity of .54, slightly better than general ability at .53. Another meta-analysis, by Roth and colleagues in Personnel Psychology in 2005, updated that literature, and described work sample tests as among the most valid predictors of job performance.

Those studies are about tests employers give. You are doing something similar on your own: giving them a work sample before they ask. I am not claiming this is a guarantee, and the studies do not measure self-made projects. The point is that employers who care about what predicts performance already trust this kind of evidence.

What counts as proof of work

It does not need to be big. It needs to be real, specific to the role, and easy to open.

- For a developer: a small working tool, or a fix to a real open source project, with a short readme.

- For a marketer or writer: a one-page teardown of a company's landing page with three changes and the reasoning.

- For a product person: a short memo on one problem in their product, with a rough sketch of an idea.

- For a designer: a redesign of a single flow, with before and after and your reasons.

- For sales or operations: a draft process, a short plan for their first 30 days, or a clean spreadsheet that solves a problem they have in public.

The common thread: it is about them, not about you. A generic portfolio shows range. A project aimed at their problem shows you already started the job.

The build-for-them method

1. Pick the team, not the posting. Choose a company where you would honestly like to work. Read their product, their blog and their open roles.

2. Find one real problem. Something small and visible: a confusing screen, a missing report, a slow step. Stay with what you can see from the outside.

3. Make a small thing in a few hours. Do not spend weeks. If it takes longer, it is a side project, not an application.

4. Write a short note. Three lines. What you noticed, what you made, and a link. No pitch, no begging.

5. Send it to a person. Not a general inbox. A hiring manager, or someone on the team the work would help. If you do not know who, see our guide on asking for a referral without being weird.

6. Keep it honest. Say it is your own take from the outside, and that you may be missing context.

What can go wrong

- Free work for a company that did not ask. If a request grows into a real project, stop and set a limit. A small sample is fine; a full unpaid job is not.

- A critique that sounds like an attack. Lead with what works. You are offering help, not grading them.

- Using their private information. Only use what is public.

- No reply. It happens often, even when the work is good. Add the project to your portfolio and use it anywhere you apply.

Many take-home assignments can ask for a lot of work too. For how to handle those, see the take-home assignment guide.

Pedigree still matters, a bit

Let us be honest: a famous name on your resume opens doors, and some employers filter on it. Proof of work does not erase that. What it does is give a recruiter or hiring manager something to say yes to when the resume alone is not enough. For many people, that is the difference between being ignored and being asked for a call.

If your resume is not getting through, start with the ATS resume guide. Then make one thing, small and real, and send it to one person.

Never job hunt alone.
