I was actually made to wait from morning 11 am, and the interview actually happened at 6 pm and My mobile was also they had taken and kept with them when went inside in the morning as I had forgotten to take my ID card, I was in stress due to all these happenings so I was unable to answer even the basic questions. However after 10-15 days they called me and said if am willing to join immediately. I had to forgo the offer as I had already started working in a different company.
