Fairly standard and very behavioral. They really want to see the way you think and that you can explain and defend your argument. Definitely know your resume and your thought process.
The 1st round phone interview was more technical which was unexpected. otherwise they just asked lots of behaviorals that I'd prepared answers for. difficult for the technical aspect of it
15 min phone interview, superday with 4 employees. Standard questions: why MS, why sales and trading, brainteasers and math questions. Overall very smooth process and HR was very accommodating, and heard back very quickly.
