ALTEN interview questions

Very unprofessional software developer consultancy company. They don't have any intention of promoting their company to possible new colleagues. It was almost like they hate being there. They didn't even introduce themselves or introduce the company. I have been directly asked about my notice period, my salary expectation and some disconnected unrelated questions at this level of the interview. Pretty weird! They didn't give me any chance to ask questions to them. I had to make my way to ask about what they do, how do they collaborate with their customer companies in the end -- almost by forcing my question's way in. The interview was completely empty.
