Microsoft Software Engineer interview questions

onsite interview. Interviewed together with 15 other students. Four rounds of interview in total. Each round consists of a few behavioral questions with one technical question. Questions were fair on bit manipulation, concurrency problem on adding a node to the linked list, and finding the missing integer in an array for some range.

Got this on campus through the on campus career fair. Interview by an experienced software/hardware engineer. His impression of me was that my background didn't quite fit the software position. I didn't get the next level interview.
