Microsoft Data Science interview questions

Three rounds, first based on resume and basics of machine learning, second and third based on competitive programming. The questions in the second and third rounds were mostly based on link list and trees.

1 hour phone screen with general DS/ML questions followed with full day on site loop. 5 1 hour interviews in total. I didn't really know what to expect going in and got a pretty wide range of questions. Topics involved data structures & algos, experimentation, dealing with dirty data, & lots of statistics/machine learning questions. Overall everyone was really friendly sharp & smart. I also had a few curveball questions thrown my way where the interviewer was trying to see if they could catch me off guard.
