How recruiters advise clients on short, fair, job-related skills tests, avoid tests that look like free work, and prepare candidates to do their best.
A good skills test is short, directly related to the work the candidate would do, given to everyone at the same stage, and scored against criteria agreed in advance. Advise clients to keep take-home work to a few hours at most, never ask for real work they'll use, and save the test for candidates who have already met the hiring manager. Then prep candidates on the format, the time limit and how the work will be judged.
When the role depends on a skill that's hard to judge from conversation: writing, financial modeling, coding, design, data analysis or a technical trade. A test can also help a client compare finalists who interview equally well. It makes less sense for senior leadership roles, where a track record and references say more, and as a first step for passive candidates, who may simply decline. If the client also uses personality assessments, agree on how the two will be weighed.
Candidates are rightly wary of tests that look like free consulting. Steer clients away from asking for work on a real, current project or anything they could use without hiring the candidate. Use a past or invented scenario instead. If the client wants a substantial assignment, suggest paying the candidate for their time. Rules vary, so the client should check with employment counsel if they're unsure.
Ask the client before the test and tell the candidate clearly. Many roles now involve AI tools, so some clients want to see how candidates use them, while others want the work done without them. Either policy is fine as long as it's stated up front and applied to everyone.
A few hours at most. Strong candidates with full-time jobs often decline anything longer.
Not usually for a short test. For a substantial assignment, paying the candidate is fair and keeps good people in the process.
After the first interview, once the candidate is interested and the client is serious about them.
