Microsoft Software Development Engineer interview questions

It interview process was not right according to me since the people who were interviewing were not much in the touch of DSA and I was expected to answer according to what they know.

It was an OnCampus Drive at NIT. The first round was Online Assessment where 2 simple DSA questions were asked. 43 Students were shortlisted in the first round. The second was the technical interview round, where a medium-level DSA question were asked. In the third round again DSA question of mid-hard level were asked. Final Round HR+DSA, a problem on string implementation(lot of corner cases) were asked for first 15min, then 15min HR round.
