Dear Lokesh, Why do you wish to conduct all three rounds on the same day? What is the logic? What is the average duration of the interview?
Anyway, if you wish to conduct all three rounds, then I recommend you conduct them on Saturdays. The rounds can start at 0800 or 0900 hours (USA time). Let us assume the average duration to be 45 minutes and the gap between the two interviews to be 30 minutes then:
Timing as per USA time:
First round: 0900 to 0945 hours
Second round: 1015 to 1100 hours
Third round: 1130 hours to 1215 hours
Otherwise, you may call the interview at 1800 or 1900 hours (USA time). However, in that case, you will have to wake up at 0400 hours (IST). Then the interviews can go on till 0900 hours (IST).
Thanks,
Regards, Dinesh Divekar
