The initial interview is a regular phone call and then the technical assessment stuff begins. A timed test (some questions to be replied in 30 mins), coding challenges (1 regular question about your expertise and 2 coding questions along with 2 testing questions all to be completed in 2 days), and a Lync call to write code on-the-fly with an experienced MS fellow, and then lastly, another couple of Lync calls to write both code and automated tests, and one call to talk to the group manager. If all goes well, one final call to interview with the director. I suggest that candidates should investigate some MS interview questions and answers which exist on the Internet.
