Take-home assignments have always been controversial — pre-AI, the complaint was time investment; post-AI, the complaint is "how do you tell who actually wrote it." Most companies have not abandoned take-homes; they have changed them. This guide covers what shifted and how to do them well in 2026.

## What companies are doing differently

- Shorter assignments (2–4 hours instead of 6–8) so the time cost is more realistic

- Explicit policy on AI use: required, optional, or prohibited

- Evaluation focus on design choices and write-ups, not just code

- Follow-up live discussions where you walk through your decisions

- Open-ended scope: they want to see what you ship in N hours, not whether you finish a fixed spec

## The disclosure question

Most companies in 2026 take one of three positions:

- AI required means "Use whatever tools you would use on the job, including AI." Most AI-shipping companies (Cursor, Linear, Notion) take this position.

- AI optional, disclose means "Use AI if you want, tell us how. We will read the code with that context." Common at mid-tier companies.

- AI prohibited means "We are evaluating your unaided skill." Less common in 2026, mostly at companies still adjusting.

Whatever the policy, follow it. Mismatch between stated policy and actual practice is a fireable offense at most places.

## The new evaluation criteria

Reviewers in 2026 read your submission with these questions:

- Did you understand the problem before writing code?

- Did you make defensible design choices? Are they explained?

- Did you handle edge cases? (AI-generated code often skips these)

- Did you write meaningful tests?

- Did you ship something working, not "almost done"?

- If you used AI, did you verify or just paste?

## The README is now load-bearing

In 2026 the README is more important than the code. It should answer:

- What did I build?

- What design decisions did I make and why?

- What tradeoffs did I face?

- What did I cut for time?

- If AI was used: how, where, and what I verified

- What I would do next with another 4 hours

A clean codebase with a thin README often loses to a less-polished codebase with a thoughtful one.

## Live walkthroughs

The follow-up is now standard. Reviewers ask:

- Walk me through how you approached this

- Why did you pick approach X over Y?

- How did the AI tooling help or get in the way?

- Show me a piece of code you are not confident about

- Write a small change live to demonstrate you understand the codebase

Junior candidates who pasted AI output without understanding fail this round visibly. Be ready to explain every line.

## Time management

- Take the stated time at face value. Going 50% over is normal; going 200% over signals you missed scope.

- Track your hours and disclose them in the README. Reviewers respect that transparency.

- Cut scope before you cut quality. A working subset beats a broken full feature.

## What good submissions look like

- Clean, readable code with sensible naming

- Tests for the core happy path and a few edge cases

- README that explains design decisions

- Transparent disclosure of AI use

- Acknowledged tradeoffs and "what I cut for time"

- Working, deployable, with a one-line run command

## What separates senior from staff

Senior submissions ship a clean implementation with thoughtful tests. Staff submissions also discuss the production-grade considerations: observability, deployability, scaling, security. Even if those are not implemented, mentioning them shows the lens.

## Common failure modes

- Pasting AI output without verification (reviewers can usually tell)

- Over-engineering the obvious path while leaving edge cases broken

- Missing the README entirely

- Going 4x over the time budget

- Implementing the wrong feature because you did not clarify ambiguity

- Dishonesty about AI use that becomes apparent in the live discussion

## Frequently Asked Questions

### Should I always disclose AI use?

If the policy says optional-but-disclose, yes. If the policy says required, you do not need to disclose every line, but mentioning the workflow is appreciated. If prohibited, do not use it.

### Is it ever worth declining a take-home?

If the time ask is unreasonable (10+ hours) or the company's reputation is poor, decline politely. Most reasonable take-homes are worth doing if you are interested.

### How do I handle the case where AI gives me obviously wrong code?

Verify, fix, and document. The verification skill is the signal. A submission that catches AI errors and corrects them stands out.
