Some firms may ask you specific and detailed questions about your grades in college or business school, even if your school policy prohibits such questions. At other firms, interview rounds may be interspersed with seemingly casual and friendly dinners. While these dinners are a good opportunity to meet your prospective co-workers, your seemingly genial hosts are scrutinizing you as well. In asking technical questions, the interviewer wants to judge your analytical and technical skills. As you go through recruiting in finance interviews, understand that you compete with yourself.
Most firms are flexible enough to hire people that are a good fit.
Although bankers may have reputations for being aggressive individuals, don't act that way in your interview. In other words, interviewers will try to suss out what your attitude towards work is like, how interested you are in a career in the industry, and how interested you are in the job for which you are applying particularly. As a general rule, you should emphasize how hard you have worked in the past, giving evidence of your ability to take on a lot of work and pain. You don't have to make things up or pretend that there's nothing you'd want more than to work 100-hour weeks. In fact, interviewers are sure to see through such blatant lying.
