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 is the instruction that I pretend that the two interviewers are my colleagues and that I should demonstrate my collaboration skills while coding. I was repeatedly interrupted with suggestions, try this, etc. that 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. Also, don't bother requesting accommodation for a disability - they'll ghost you for asking.

First, a screening call, then a hiring manager interview, then a panel of 3 1-hour technical interviews with members of the team I'd be joining, and an interview with Product Managers.
