SGK Obiee Developer interview questions

There was initial screening by talent Acquisition team, then there were 3 1:1 interviews with Enterprise Architect , Sr Application Development and KPMG Consultant. All of the rounds were one after another 45 mins each and that was really very unprofessional , my interview started at 9AM and was complete at 11:20 , No-one was asking even for water during my interview.. all came and started discussions. I felt there should be atleast 5 mins gap , but it happened there that one was waiting outside for other to finish. Ok, the interview went well and mostly questions were technical in nature abut were How-to based questions. Few questions were What? questions like wat is architecture of OBIEE, what are the best practices involved in development what is initialization block etc..
