Microsoft Software Engineer interview questions

The first interview I had was with a college recruiter, which went well. It was more behavioral in nature. I was contacted back about a month later and told I had the opportunity for a second-round interview at their headquarters in Seattle. There were four interviews asking about coding questions. I feel the first interview was the most important and I hear this is how they gauge your skill level and will communicate this to your next interviewers.

I've applied online and after two months I've received a mail to sschedule a phone interview. The interviewer said that the interview will last 30 min. After that, they booked me a flight to prague and had an on site inteview at the skype headquarters that lasted about 5 hours.
