Microsoft Technical Support Engineer interview questions

The interviewer is conducted on Skype due to oversea's position. Time of interview was 40-50 minutes. 10-12 questions. To prepare for this interview, I assort about 10-15 Microsoft interview questions and most of them are what I received as interview question. However, some of questions that have no correct answers are hard to answer, it is definitely best to think and prepare them before interview.

1 round have to answer 12 questions on the phone. 80% correct rate will earn you a ticket to the 2 round. 2 round talk to a senior support engineer about troubleshoting questions 3 round onsite to meet the team, last round was still tough, I was asked a lot tough questions like from the windows networks to windows clusters, from software to hardware tuning
