A quick process: a screening interview, then a coding challenge on a code test website. The challenge was intended to be difficult to impossible. I was told that no one passed.

Making the challenge more difficult was the instruction that I pretend the two interviewers are my colleagues and that I should demonstrate my collaboration skills while coding. I was repeatedly interrupted with suggestions like, "Try this." It was difficult to proceed.

I was told to ask questions and discuss my train of thought—something one naturally doesn't do in an interview for fear of saying something wrong.

At the one-hour mark, suddenly everyone had to attend some other meeting.

Collaboration occurs during design meetings and whiteboards, not while you are heads-down coding. It's no wonder nobody passed.
