Microsoft Software Development Engineer In Test SDET II interview questions

Interview was scheduled by a recruiter. There was phone interview and then called for in person interview. Had to wait for an hour at their office to get the interviewer's time slot. Interview process is not properly organized. Later, I had go from room from to meet about 5 managers (or leads) and talk to them. They don't seem to be prepared for interviewing me. I could easily answer their questions. It seems I was turned dow because I'm a Java guy and their work is mostly around .Net.
