Nagarro Senior Engineer interview questions

Total 3 rounds. 1 round for IQ test and 2 rounds of interview. The first interview round was great. Discussed about past project and had some questions based on that. Interviewer had asked a scenario based question for ServiceNow platform which was unique, and I have yet to come across a question of similar difficulty in my interviews. Definitely felt they are technically sound and knew when I was wrong. The second interview round didn't seem to go as well as the first, but still was offered a Senior role. Had to decline as I felt I was not ready to be a Senior yet (3.7 years experience). Would like to interview with them again in the future if allowed.

Aptitude test followed by two rounds of technical rounds. Second last round was a managerial round with directors and finally the HR round for salary discussion. After clearing all of these rounds the offer was rolled
