There were 3 technical rounds and 2 techno-managerial rounds conducted for the post of Senior Software Engineer. The techno-managerial rounds were straight forward with an aim to understand your comfort level with the technology you have worked on. They were also interested in knowing if you can work in a team and play a key role such as a manager in the team. So be clear on the technologies you have worked on and try to be honest with the interviewer, if you don't know about something it is fine don't tell them the complete ABCD just say you are not comfortable with that ques/problem.
