I went for .net developer position at their Bandra branch. Though there are 5 branches in 5 countries, and for india its in BANDRA. There were only 7-8 employees, small office and the interview was supposed to be conducted online via skype at their office, but before the interview they kept a condition, which if accepted only then further interview would be conducted, which i refused and the interview was over. The condition is specified in the most difficult question
