They sent me a coding challenge (Codingame) that was 2-2.5 hours long. I have finished most of the tasks and given a partial solution to a few. I suspect no one even checked the code personally, they just looked at a very strange summary screen from Codingame that doesn't reflect the result well at all. Recruiter has never replied to any of my emails, neither before the coding challenge, nor after. Just a waste of over 2 hours of my time to not get any response.
