MGH Group Software Engineer interview questions

I was interviewed 3 times: First: It was a technical interview. Two developers asked my field of interest and the questions based on that field. 7 were chosen out of 20 candidates. Second: This interview was purely with HR. She asked me about my background and salary expectations. Only 3 were selected. Third: A written exam for 30 mins. General knowledge and IQ.

I was interviewed through campus placements. 1st round was a written test 15 easy questions on java 2nd round was a chillax interview(rejected cause I seemed more interested in working under sales sector in their company rather in IT field---I guess) 3rd was technical round
