Microsoft Program Manager interview questions

Micorsoft program manager is actually the product manager position. Two phone interviews before onsite. It was a little bit surprise to me that MS is looking for very technical product manager with a need of being able to write code and do the system design.

1st Round Campus Interview so far. Have not heard back, it has been about a week. Interviewer was a bit emotionless, hard to gauge what he was thinking. Offered no advice during technical question.
