Totally unprofessional. I believe the interviewers had no formal training on how to take an interview. Walking out the room talking on the phone etc., random people come in ask a question and go out and then again come in. A bunch of novices trying to act smart.

Then also for the sake of readers there were random flashing question like method overloading, overriding, what will happen if I have multiple main methods, can we override using qualifiers etc. their initial coding round was OK(or rather good) but after the F2F interview I felt that they are looking for people from service industry. I expected it to be more on algos and logic. but sorry it was the same old service based company question. No regrets I just had over expected.

Really... It didn't have any.
