Microsoft Software Engineer interview questions

Was contacted by recruiter who found my resume online. She suggested two positions in kernel team and search team. After I agreed phone interview was scheduled. It took about 30-40 minutes. Recruiter was very positive. Nothing really difficult. Experience question. Generic C knowledge, a couple (or one) brainteasers. One of the questions was which MS products did I use and how I would improve them. I didn't use any extensively so I mumbled something about plugins and that's it. Got polite "do not fit" email next day.

Everything went smoothly in terms of planing. Very good communication between the recruiter once the initial screen process has started. Great accommodations and all expenses paid. Went through a campus interview, phone interview and on site interview. All interviews were very much the same, 5 minutes of personal background and 30-55 minutes of skill test. The interviewers were very polite and asked questions of different difficulty, each in their own sphere.
