The best engineers are likely not using that. Most of them get burned, and you're mostly left with engineers that are reallly good at marketing. I could be wrong. I tried it for a few months. I only got one question, and I basically helped a guy understand docker for free during the evaluation. I guess someone needs to start an upwork for serious people.

We did churn our share of low performers at the beginning. I'd say 5 of the first 10 hires stuck (most of the churn was us terminating the relationship). The ones that stayed were able to refer a friend or two.

Also, another downside: fraud. We ran into 2-3 folks who were operating outright scams, ranging from an agency posing as an individual, to identity / account theft.
