Microsoft

The interview process took around a month. I had a phone interview where I was asked to test a calculator. The on-site interview included linked list problems, search, and string algorithms. The HR contact was always very friendly and kept me post

I received an email from a recruiter and set up an interview over Skype.

The interview was filled with lots of programming questions. It was not nearly as challenging as Google's, which ultimately led me to the conclusion that I didn't want to work there. The folks who interviewed me were pretty friendly, though.
