My recruiter informed me that I will be called for an interview within the next couple of days or so. HR called me and set up the interview. I went there and interviewed with 3 people. The first 2 people conducted technical interviews where I was offered a pencil and a paper to solve a programming exercise nothing complicated. It dealt with C pointers. Then the other person asked general questions about C++ and object oriented programming concepts. The third person who interviewed me was from HR and she asked few behavioral questions and mostly talked about the great benefits the company offers. I did not like the atmosphere there it seemed like a "big brother" environment with cameras and surveillance all over the place. Additionally, it seemed like most of the technology used in the company in-house and using C or C ++ and one of them mentioned Fortran which gave me the feeling that in terms of technology I won't be learning much but on the other hand I might learn about the financial markets. The interviewers were one was nice and the other was neutral. a week later I was offered a position but by then I already accepted another offer.
