went for an interview, waited for around 20 mins, got inteviewd, got called for a second intervirew, that one was about 10 mins, they said they would call back within 10 days, they called again, i went for a third and fourht interview.. after four interviews i got the job. it was totally worth it. my advice is, if you get chose for an interview, go and try your best no matter how long it is going to take you
