Nagarro QA Automation Engineer interview questions

1 round was MCQ (aptitude) 2 round was MCQ but based on selenium, java and C programming I have applied for QA Automation java but questions were from C and C++ which i don't know

Worst interview experience ever. No management. No POC to guide candidates. 1 interviewer per 100-150 candidates. I applied through naukri.com. It was a walk-in. There was a long line for the registration process. After getting done with it, we were directed to a lecture hall as per our concerned HR. We were made to wait for 2.5 to 3 hours, with no communication of the process from their end. There was no POC, people started leaving. Few people encountered a personnel and enquired him, and were told that you need to go to the fourth floor for the interviews. We went there, and were made to wait for another half an hour. Then a person was called for an interview. Mind it, there was just a single interviewer for nearly 100 candidates. No initial screening was done. Direct f2f. I was the second to be called. He asked me my current roles and responsibilities. He told me he was looking for people with proficiency in Java or C# (I was working in Ruby). When I said, I can do it. He asked me if I could handle dynamic web tables. I told him, I could tell him the vague syntax and the logic. He told me he doesn't think i know automation at all and asked, if I would want to interview for a manual position. When I said no, he asked me to leave for the day. Only two candidates were interviewed and other people waited for another half an hour, as the interviewer didn't receive candidate's CVs from the management people. Worst ever.
