I submitted my Resume at a Career Fair and got contacted by a recruiter to do a phone screen. That was all business as usual. I then got invited out to the Microsoft campus to do a series of interviews (I was told between 3-5 for intern interviews). All expenses paid, etc. Overall pretty solid. Third interview was the hardest and I think is the one that prevented me from getting an offer. Fourth interview asked me a lot of questions related to vision/the future which I thought was interesting. Unfortunately, she only gave me a little over half the time of a regular interview because she had to go to a meeting or something. Unfortunate and frustrating because I felt rushed and don't think I was able to fully make up my lackluster performance from the third interview.

Three rounds of interview starting with phone screening, middle round of online interview and final round of three interviews all schedule within a couple weeks time. Interviews were Microsoft recruiters followed by employees
