Capgemini Java Senior Developer interview questions

I received an email from employment website and it provided me an Elevator login page to book a slot. After I got my slot booked, there was no confirmation from the company about my interview. Even then I appeared for an virtual interview, the interviewer joined 35 mins late without any acknowledgement and the interview was really horrible since the voice of the interview was not clear at all, He had complete network issues since he was somewhere outstation with too much background noise. I could not understand any of his questions and he did not agree to reschedule after informing him the glitches, I got rejected
