Beware of the interview process of Nagarro. I had given couple of interviews but experienced unprofessional behaviour from the recruiter. Recruiter is fraud , he asked for documents and then did not reply to any of the emails or phone calls , not even gave any feedback. Very hopeless and pathetic behaviour from recruiter, don't waste your time here.

Asked basic dsa,OOPs,questions from Linked List , Array mostly and projects . Then in HR round , basic intro , effect of AI , traditional or Digital mode of classroom.
