Got recruited on linkedIn and told to send my resume. Had a phone interview a couple weeks later just having me describe what I do at my school IT job. Couple weeks later, received the email that they are flying me out to Las Colinas, Texas for the interview. The day before the interview, they set up a social dinner where you can eat/drink and talk to other people interviewing as well as current employees of microsoft who will be doing the Interview. Highly recommend attending this as it calms your nerves a lot and lets you get to know some of the microsoft employees before they interview you. The interview was the next day with a morning session and an afternoon session. My guess is there was about 20-25 people per session. You then have 4 separate one on one interviews each about 45 minutes long. Interview mostly consisted of me explaining what i've learned in school and my internship. I didn't receive any technical questions, mostly just be confident in what you're talking about. But make sure to ask them questions too, make it more of a conversation then an interview. Received my offer 2 weeks later. Can't wait to be starting at the largest software company in the world!
