Recently I had done interview with ATC gurgaon.1st round was technical 2 was hiring manager and 3rd is HR.my experience was very bad after clear all round even sumbit the all required documents to hr,after 1 week follow-up with HR said we can't realse your offer letter just because our upcoming project is on hold,Such a unprofessional people in this company.never recommend to anyone.

It was a short and brief interview. 3 Rounds of the interview. 3 Technical and 1 managerial round. They generally ask a question based on the skill set of a candidate. And they usually keep it short.
