Perguntas de entrevista de vagas de Java Developer da empresa IGATE

I already read reviews from glassdoor about the interview process, my stupidity i took risk and went for interview. They scheduled interview at 9:30, i reached before time and submitted profile. Now the drama started, They were following LIFO process. after 2 hrs we asked them about our turn, HR said ohh when did you come..where is your resume..what is your name...Damnnnn irritating.. candidates who interviewed first went directly for f2f and For rest of the ppl, they said so many candidates has come so written round will be there. After written, they told us to go for lunch. Post lunch they said, leave for the day. They ate our time since 9:30 to 3:00. J.S.
