Microsoft Intern interview questions

Was referred by a friend who had worked there the summer before. I sent in my resume via email and was asked to do a 30 minute phone interview. A couple weeks after the phone interview, received an email asking me to come to the second round of interviews in Redmond. While there, they were extremely nice in the amenities -- great hotel, food budget, transportation, etc. During the day, had a total of 4 approximately hour long interviews where learned about Microsoft and was also asked one or two technical questions.

For our campus recruitment, there were multiple rounds of interviews. First there was a written aptitude test, then there was a coding test. If you clear both of them, you'll be called for personal interviews. There are 3 levels of personal interviews. The initial 2 rounds are technical interviews and the final one is the HR interview.
