Microsoft Software Engineer interview questions

First rounded consisted of about 50 questions on aptitude which we were supposed to solve in 45 minutes.This was followed by technical round,which had questions on DS,OS,DBMS,C++,C.Then came the technical interview followed by the H.R round.The questions in the technical round were easy as well.But they asked in depth about the resume.They mostly checked us on our basics of DBMS and DS. Although I could not make it to the H.R round,but those who made it said it lasted for about 15 minutes and it was a good experience.
