Microsoft

I had a phone interview with the hiring manager. He was really nice and supportive. He asked questions about my background and what I do at my current company. I explained it well. Then, there was a coding question: write a program to add a node to

Three interviews, including one general interview. All three interviews, even the one at the GM level, were technical, involving algorithms and writing code on a whiteboard. They included optimization questions, testing possibilities, etc.

It was five years ago. I had really forgotten the questions. They were not hard. Questions like reversing a linked list, etc. It took five hours, too long. After all, a director asked me for coffee. It ended up that two teams gave me offers.
