Left a comment above, but thought I'd ask again... anyone have any experience with GroupTalent [1] which seems to enable this type of small-contract-as-an-interview process?
Hi - I am the founder of GroupTalent. Mahmoud above has had experience on the hiring side of our platform. I can put you in contact with other devs (with their approval of course) who are doing try-outs and they will relate their experience directly.
