Microsoft Software Development Engineer In Test SDET interview questions

Hiring through career fair at top-tier school. Skype interview first and then on-site at Redmond. Skype interview was for PM position and was pretty straight forward. 2 weeks later got contacted for final round. A couple of days later my application was changed from PM to SDET. Even though I didn't want that position, I decided to go and find out more about Microsoft. Final rounds was 3 interviews (1 SDE, 1 SDET, 1 PM) and lunch. A fair amount of coding and a full behavioral with the PM.

This was a very standard interview process where I received a phone screen by HR, then a phone screen by an engineer, and then finally I was flown out to the location for around four interviews lasting an hour each. There was no lunch break as the interviews were from 1-5pm
