I applied through college or university. The process took 1 day. I interviewed at Cognizant (Calcutta)
Interview
The process started with the officials from cognizant giving a brief presentation about the day's process and the organisation's overview. Then first they had a technical round. Upon passing the technical round the candidates went through an HR round. If you clear both, they send you the offer letter.
Smooth interview process as well as it was very interesting with ample feedback at the end. I enjoyed the conversation a lot and coverted the interview and accepted the offer.
