Technical interview first (and only in my case): some coding exercises, some design questions. Left alone in a room for 1 hour and a half with the goal to solve as many exercises as possible. Not possible to discuss with interviewers. Then debriefing with interviewers very rude: I don't mind being wrong but there's a way to say it and not insult people. Even if I had succeeded the exercises, I would not have wanted to join.

Implement a thread safe cache. Design a banking account system. And 5/6 other exercises I don't remember.
