> I passed the first interview, but the second was going to be a 5-hour remote codeshare/whiteboard interview with the team. I declined the second interview.

Last year I interviewed for MongoDB. They proudly boasted that their hiring process consisted of a 7 interview marathon. I asked if that wasn't too many interviews, and the interviewer boasted that they already managed to streamline their process down from 12 interviews.

They also proceeded to point out that all FANGs follow the same process, except they really don't.

I respectfully dropped from the hiring process there and then. The extremes to which they take their cargo cult mentality is out of this world.
