They'll make you sit outside the office until your turn - typical one after another candidate interviews. The other candidates will also be waiting with you.
The interview itself is less than 5 minutes, HR staff isn't very well-versed in interviewing. The only thing they'll ask you is to "self-present" (yeah they don't speak *proper* English either, but that shouldn't be an expectation - especially in India). The interviewer will be staring daggers at you, not really sure why - or what they're getting at.
Pretty sad and dilapidated honestly.
