Infosys Java Software Engineer interview questions

Technical round: The interviewer asked very basic questions to a 4 years experienced like oops 4 principal, final finally and finalize difference... then i was like why he is asking so basic questions but then i realized he was just taking the interview for the sake of taking it..he was never going to select me.. i am saying this because he wasn't event listening as in between of me giving answers one of his colleague came to talk to him and i was responding to his(interviewer's) question, he started talking to him and asked me to carry on...i mean then who is listening. worst experience.
