Microsoft Software Engineer interview questions

Got the phone interview opportunity from employee referral. One round phone interview, asked about past projects, some behavioral questions, and several basic data structure questions including hashmap, binary search tree. One coding question which was easy.

Phone interview followed by in person interviews, there can be up to four interviews each with different goals, each interview was technical. You will not necessarily get all four interviews. One interview was had a design question, two had algorithms questions and one had an implementation question. Between the interviews you are sat with a recruiter in a room with the other potential candidates. The recruiter talked about Seattle, Microsoft.
