Microsoft Software Development Engineer In Test SDET interview questions

30-minute college technical screen (programming problem, test cases for it, and some basic behavioral questions), followed by 5 one hour rounds in Redmond. First two rounds with individual contributors, last three with managers with increasing level of seniority. Most rounds were in the format of solving one or two problems on the board and then writing test cases for them, except for the last round with a senior manager who also had non-technical conversation determining my fit with the company. Occasionally there was enough time left to discuss some of my projects or interests - especially during the lunch interview where this sort of conversation is particularly appropriate. Overall a very pleasant interview experience which I was expecting from Microsoft based on reading other reviews.
