Opt IT Technologies Devops Engineer interview questions

I gave interview to this company 4 months a ago in total there were 6 rounds 4 technical 1 managerial 1 salary discussion i cleared all the rounds and in salary discussion they said that I didn't cleared anyone of the previous round

They had 3 rounds total, first was some junior who took interview, the questions were not up to the standards, later on some guy named Santhosh took the interview it was good by the way, I cleared the interview but the package was very low compared to work they expect.
