Microsoft Internship interview questions

Had a call with HR then an on site assessment center with a group case study and several interviews with managers. group case study was very short we had 30mn preparation and 10mn presentation with managers listening to us during the whole exercise. Then interviews went very well managers were very nice and interested by our personality and background.

Got contacted by a recruiter through Linkedin. Applied through Microsoft webpage and also sent my cv to the recruiter (it was requested by him). Got a phone interview about 2 weeks later, they did not ask any personal questions, only about my previous experience and projects. Seemed to be really interested in my bachelor project, she made a lot of questions about it. Then a brain teaser which I failed, she did not seem to care too much, just explained the answer to me. Then she allowed me to ask her questions and she answered them in detail. Really nice, pleasant interview. She told me they will contact me in 3 weeks.
