Applied on their webpage and got invited to a telephone interview. Telephone interview got cancelled without warning a few times, then two separate people tried to call me. Finally managed to talk to somebody and was asked to do a sample assignment, which I did. I was then told to remove the solution from my personal github-account, lest it influence other applicants (it's a simple string-parsing exercise, nothing for which you'd have to desperately scour github at random). Complied. Received a rejection with feedback about my assignment saying that - it accepts invalid inputs (it doesn't, I triple checked) - it throws errors when you give it incorrect input (that's what code should do) - the indentation style was "very hard" to understand (two spaces. Shouldn't be too difficult.) I asked for clarification, received no reply. A day wasted. Very unprofessional. :(
