Skype Software Engineering interview questions

Applied at my university, was contacted the following week with a link letting me book a time for an interview. The interview mainly focused on questions regarding networks and finished off with an easy programming question on the same level as reversing a string(wasn't that though). Two weeks after the first interview I was invited to a day of interviews in Prague. The interviewers in Prague were very friendly, I got to do 4 interviews that were around 45 minutes each, ending with simple programming questions. If you performed poorly you only got to do 3 interviews.
