Microsoft Developer interview questions

First an online coding test on cocubes.com There were 3 questions in the test. Some who did 3 weren't selected, others who did 2 got selected, so optimisation and lines of code do matter. Results were declared after 1 week. Then a group fly, almost half of the candidates got rejected after this. Three more interviews were held the day. Final results were declared after 2 days

About half a month after the online application, I got email from the university recruiting team. I was scheduled three rounds of interviews on the same day. The interview questions were not very hard, two of them are about data structure and one is about HTTP. After the interview, I got the offer on after a couple of days through phone call. The entire process was smooth and interviewers are very kind and friendly.
