When does an interview task become a whole unpaid project?
A short task can show how somebody approaches work more clearly than another interview question. The difficulty is knowing where a reasonable assessment ends. A vague brief, several rounds of revisions, or work that looks ready for real customers can demand a lot from someone who has no offer yet. What boundaries would make these tasks fairer? Clear timing, a defined purpose, and an explanation of how the work will be used would help applicants decide. It should also be possible to ask about an alternative when a task requires equipment or time somebody cannot spare.
