Trial employment (and large take-home projects) are expensive for the candidate.
I can't help but think there's way to mitigate that expense among several (dozen) companies.
Triplebyte is already interviewing for other companies, why not set a low bar and hire everyone who passes it for a week? Charge your clients accordingly. If you have 25 clients hiring for overlapping skills, have them all pay to hire a person for a week.
40 hours of of labor / 25 clients = 1.6 hrs of labor per client, or about what it costs to do a single technical interview.
Meanwhile, the interviewee gets to do a single, focused project for a week, but effectively interviews with 25 companies!
I can get on Dice right now and find over 100 openings for python/java/golang/javascript/c++ engineers, certainly all of those companies would benefit from something like this.
More power to Triplebyte if they can figure out how to take those projects and turn it into a client deliverable on top of defraying interview costs.
