I had 5 technical interview 4 of them are in depth technical interview plus a management interview so 5 in total if we did not count the technical question on the very first introduction call . to not get an offer . They wasted so much of my time and effort I promised my self after this not to work for PA in my life even if i have to stay unemployed . as I feel they request no time for engineers if they did not like my technical knowledge why keep doing more and more and more interviews .

1st round, HR screening. 2nd Rd: Manager and Technical Panel 3rd: Manager/Sr. Manager and Technical 4th Tech round. If company feels they still not sure and wants to interview you. Else directly final salary discussion. 5th: Salary discussion with HR.
