I passed their tests, spent 50 unpaid hours on a coding assignment, for which I learned react native (not a requirement) and got passed over because their requirements were poorly worded and I didn't ask for clarification (it's a coding assignment, why shouldn't I assume they can at least spell out their own requirements well.)

They'll give me another shot at it, but honestly it's not worth the effort. I discovered from the engineer that the average asking rate for the other 70+ developers in Canada is $45/hour. I'm not going to work for that - as a "top 3%" developer it's so much easier to make $65+/hour full-time, remotely. Why would I settle for sporadic work and lots of risk for less money? Do yourself a favor and steer clear of those guys if you know what's good for you.
