Microsoft Software Development Engineer In Test SDET Intern interview questions

Microsoft is really good through the interview process. I applied through my college recruiter. I had one interview on campus. It was fairly easy. I was told that I would fly out to Seattle a day after the first round. They contact you well ahead of time and send you detailed instructions about the interview and your trip. The interview process is well oiled. There are four rounds of interviews, with only the first one being easy. I was asked two questions each round. There were real world problems, object oriented design and run of the mill programming questions. The interviewers were a mixed bag, some helpful and some untalkative.

I was recruited at college and had a quick one-on-one screen before being sent off to the Redmond campus for a full-day of interviews. I interviewed with four different people at the same division (Microsoft Advertising). I had on average two questions per interviewer. The questions weren't particularly difficult -- you could tell they were not actively trying to weed out candidates. That said, they were somewhat tricky and required some thought behind them. They were abstract questions that most students studying CS should be familiar with (write a program that finds the most frequent word that appeared in a long string, write a program that finds the shortest distance between two nodes on a tree). Because I was interviewing for an SDET position, it was prudent to show that you thought about edge cases and ways to test your program once you designed it. After my interviews, I was taken back to their college recruiting building and given a briefing. I was not offered an internship on the spot, but they got back to me relatively quickly, after a weekend.
