There were 4 rounds of interview. First was a basic telephonic technical interview after that they called me for f2f interview. When i reached the day they were busy with some of their deliverables so i been told to come again. Next day when i reached there was 2 technical interview and one managerial. It was mostly related to c/c++ and basic algos. After that i was told you are through with both rounds and one director will meet and explain. I waited for the director call but i have been told he was out of station so i got a call for director round after a week and they told me to come to their office again. On this day there was a f2f interview and the hr told me that its a basic meet in which director will explain the process here comes the shock the guy was fighting through out my interview with other colleagues for the meeting room. After every 5 min someone was coming and claiming the room and he was telling everybody that they cant reserve room since it can only be reserved by senior manager and above. Then he turns towards me started asking technical questions. He told me code a parking system with all the industry standard on the whiteboard. And he was asking for better algos everytime. If i use vector then question was why vector why not array or list e.g. After that there was no call from there side for 3 days when i enquired they told me you are not through.
