Microsoft Software Developer Internship interview questions

The process started with a phone screen to assess behavioral fit. Next there was a short coding challenge. Then I moved on to a virtual onsite with two technical rounds. All in all the process took ab 2 months.

Technical interview with 4 algorithm tasks. 1 regarding arrays, two with linked lists and one with binary three. The one with the binary three was the hardest one. I managed to solve all of them for given test cases, but the performance I provided was not good and probably that was the reason why I didn't get the offer.
