Paid Trial Projects: The Smartest Way to Hire Developers

Interviews measure how well someone interviews. They tell you almost nothing about whether that person will ship working software in week three. A short paid trial project fixes this: two weeks of real work, at real pay, on a real task. It is the single highest signal hiring tool available to a founder, and most founders still skip it.

Why interviews mislead

Polished talkers outperform quiet shippers in interviews, and the correlation with actual output is weak. The problem got worse recently: AI assisted interview fraud is now common enough that a flawless live coding session proves less than it used to. Meanwhile some of the best developers you can hire are mediocre at selling themselves in a video call.

Reference checks help a little. Portfolios help a little. But nothing predicts how someone works with you like a week of them actually working with you.

How to scope a one to two week trial

The trial task should be real work from your backlog, self contained, and not on the critical path. Good examples: a CSV export feature for your admin panel, a Stripe webhook integration, a settings page with three or four options, or clearing a batch of well described bugs. Bad examples: anything touching your core data model, anything vague, anything you need finished by Friday no matter what.

Write a clear definition of done before you start. One paragraph: what the feature does, where it lives, and how you will check it works. Cap the engagement at either a fixed week or 10 to 20 hours so both sides know the commitment.

What to actually measure

The code matters, but it is only one of four signals:

• Communication: do you get short, clear updates without chasing, and do they flag problems early rather than the night before the deadline.
• Questions asked: strong developers ask two or three sharp questions on day one. Silence followed by the wrong thing built is the most expensive pattern in remote work.
• Shipped quality: does it handle edge cases, does it include tests, does it work on the staging link you can click yourself.
• Estimate accuracy: did the work land roughly when they said it would, and if not, did you hear about it early.

Pay the full rate

Pay your normal rate for trial work, not a discount and never free. Unpaid trials filter out exactly the people you want, because good developers have options and will not gamble a week of income on you. At African rates of $20 to $40 per hour, a part time trial week costs $300 to $800. That is the cheapest hiring insurance you will ever buy, compared with the months of salary a bad hire burns.

Converting to a long term engagement

Decide within two or three days of the trial ending, and tell the developer either way with honest feedback. If it is a yes, do not jump straight to a six month commitment. Extend to a month, then a quarter, raising scope as trust compounds. If two candidates both did well, it is completely fine to have run parallel trials on different tasks and hire both or pick one.

Get the legal basics right

Sign a simple contractor agreement before any code is written. The two clauses that matter most: the work is made for hire, and all intellectual property assigns to your company on payment. Add an NDA if the trial touches sensitive data. Pay through a platform or traceable channel so there is a clean record, and make sure the code lands in a repository your company owns from day one.

A week of real work tells you more than five rounds of interviews ever will.
