Met at job fair, had about a one hour in-person interview on my campus soon after where I wask asked about my resume and background and a few simple coding tasks concerning strings. This man was very charismatic and happy to be working at Microsoft, he was quite different from the interviewers I met in Seattle, but he did his job well and made me excited to work there.
Was later contacted for an on-site interview in Seattle. Was flown in for an overnight stay and went through 4 interviews the next day.
The first one was easy, a few operations on linked lists, although the interviewer did not seem excited or happy to be doing the interview, seemed like he just drew a short straw.
The second was worse, the interviewer seemed to have a large ego and felt the need to correct everything I said (including things like why I like programming and what my favorite project was), I just attempted to remain polite. He asked me about finding the largest consecutive sum in an array. Although I managed to put something together, I do not feel it was what he was looking for and he showed me his solution which I questioned and never got a satisfactory answer for (I was afraid to push him further because we were short on time and he seemed very firm in his ideas and I was far too nervous and tired). I don't feel he fully understood the question he asked me himself and that he just chose it from a list.
The next interviewer I had lunch with, then a few more questions such as iterative and recursive fibonacci, approaching new code, etc. He also had a piece of paper and seemed to be choosing questions from a list. He was young and personable although he seemed very tired and beaten down.
My final interview seemed to be with a higher-up manager, he was older and seemed to have more influence over Windows 8 features (he was able to point to some of the decisions he had made on the tablet interface). He was very laid back and didn't really ask anything specific. Rather, he simply asked what I liked, then discussed it, asked for some code examples. He seemed very experienced in giving interviews and somewhat jaded about it, but nothing too difficult.
