Why Assay

Tired of no reply?

You send your CV. Nobody answers. Nobody tells you why. Here, experts read what you built and tell you how you did.

  • Use any AI tool

    Claude, Cursor, Copilot, anything. It is not a trap. Use AI like you do at work.

  • We read how you work

    We read your plan, your code and your AI chats. We see how you think.

  • Everyone gets feedback

    Marks out of 5, plus a written note on what went well and what to fix.

  • Not a puzzle. Not public.

    No LeetCode. No trick questions. Your grade is not on any public list, and your code stays yours.

  • Good for juniors too

    New to the job? Show what you can build, not just a CV.

  • Free in the beta

    It costs nothing to take part while we are in the beta.

How it works

Not a small take-home. A whole product, from plan to live link. The same brief for everyone. Take a few days, at your own pace.

  1. Step 1: Apply for free

    Leave your email. We send you the brief for the project.

  2. Step 2: Build the whole thing

    Scope it, plan it, design it and ship it, with AI. Take a few days, at your own pace.

  3. Step 3: Send your work

    Send us your plan, a live link, your code and your AI chats.

  4. Step 4: Get your feedback

    Experts read how you planned, built and shipped, and how you used AI. You get marks out of 5 and a note.

How you build

Use AI like you do at work.

Claude, Cursor, Copilot, anything. It is not a trap. We read your code and your AI chats to see how you work with the tools.

  • You plan before you build.
  • You check what the AI writes, and fix it.
  • You ship a whole thing that works.

Everyone gets feedback.

Marks out of 5 in four areas: scope and plan, design, shipping, and use of AI. Plus a written note on what went well and what to fix.

  1. 1Scope & plan

    Did you pick what to build first? Is your spec clear?

  2. 2Design

    Are your design choices clear? Is the code tidy and easy to change?

  3. 3Shipping

    Does it work, live? Can someone else set it up and run it?

  4. 4Use of AI

    Did you guide the AI well? Did you check its work?

The talent pool

How the talent pool works.

More and more teams want devs who build well with AI. A CV can't show that. Your project can. We're building a talent pool, so companies can find them.

  1. Stage 1: Build one project

    Show how you build a whole product.

    AI allowed

  2. Stage 2: Experts review it

    They read what you built, not your CV.

    Written feedback

  3. Stage 3: You join the pool

    Only if you say yes. You can leave any time.

    Your OK: Yes

  4. Stage 4: Companies see your work

    Companies we work with can look at it. They want AI-first devs.

    No public ranking

What is Assay?
Assay is a talent pool for AI-first developers. It is a place where companies can find them. We're starting to work with companies that hire. You get in by building one big, real project with AI tools.
How do I get in?
Leave your email, and we send you the brief. Build one big project with AI tools. Take a few days, at your own pace. Send us your work. Experts review it. Then you choose: say yes, and companies we work with can see your work.
Who sees my work?
Our team and our experts, so we can review it. Companies we work with see it only if you say yes. Nobody else. There is no public page.
Is there a ranking?
No. There is no public ranking and no leaderboard. If your marks are low, no company sees them unless you say yes.
Will this get me a job?
We can't promise that. We're starting to work with companies that hire. If you say yes, they can see your work. You get honest feedback either way.
What if I don't want to be in the pool?
That's fine. Just leave the box unticked. You still do the project, and you still get written feedback. You can change your mind any time.
Is this free work for some company?
No. It is a practice project, not a real client's work. You keep your code, and you get feedback either way.
What do I build?
A whole product, end to end. It is bigger than a normal take-home, because AI lets you build more. You plan it, design it and ship it. You get the full brief when you join.
How long does it take?
A few days, at your own pace. It is a big project, so plan your time. That is part of the test.
Is AI really allowed, or is it a trap?
It is really allowed. We grade how well you use it, not whether you used it.
Who grades my project?
Human experts, with help from AI.
What does it cost?
Nothing. It is free during the beta.
