BAE Systems interview questions

This was the first round interview, apparently they have 2 or 3 rounds, I am not sure. The 1st interview was conducted quite unprofessionally and mixed up in terms of the questions asked. The guy at Detica went through my CV asking various questions about statements on my CV and taking some words out of the context, which I found very annoying. He seem to be interested in what year I developed a particular application or used Java, etc. I found this rather strange and pointless strategy. If I want to employ someone I would only be interested to find out if he is capable of doing his job not finding out what year or month he has done something. Then he read a scenario from piece of paper which involved database design capturing UK car traffics. Now he didn't even let me have the paper, he just read it once. As if in real life development a client reads something for you and then expects you to design it right there :-) . So again I found this very strange. The design or answer to this could be anything really. You could use UML paradigm, RDMS paradigm or just a flow chart, etc. All of these could be right because at a first instance you would be looking at the very high-level design. But he wouldn't even let me think and kept interrupting some times with some silly question like what size would you choose for your string. Very stupid question, because when you are designing at a very-high level you are not concerned with size of your variables. These are the details that come afterwards. Anyway, overall it was a waste of my time and I got the impression that their job would be very boring for me because I asked the guy at the end about the job (yes I had to ask him, he didn't even bothered to tell me about the job). He didn't have anything really interesting to tell me about the job. So for some at Ph.D. level like me, it would perhaps quite boring.
