IT Convergence .NET Development interview questions

I have interviewed for a .Net developer position in this company. The first technical round was with a panel of two engineers. It went well. The second technical round was with a manager. This gentleman is the most unprofessional person I have ever come across in my career span of 10 years. He does not know what to ask about my profile, skillset and experience. Did not ask any such questions. His whole focus was on my academics marks and salary though I am a first class student throughout my academics. Infact, the most demotivating discussion which took off my interest from working in this company. After seeing this person, I got an idea of my future and how managers and the culture of the organisation would be. It's mere waste of time to attend such kind of interviews.
