They conducted walkin interview in Chennai on June 2017. HR confirmed me that I cleared the first round and they will arrange telephonic technical interview. After that HR didn't arrange second round. Even I sent an email but no response from them. Not sure why they are doing like this. If there is no requirement why they are conducting fake walkins.

First round - written second round - Face to face Third round - The managerial round was average and was short. finally, the fourth round was the HR round. The overall interview process was smooth and quick.
