The interview the bank representative is going to conduct will be to get to know you well by asking you some basic biography questions, why are you in the country, how long do you plan to stay and that sort of questions. Don't lie to the bank official, not because you'll get in trouble or something, but because you might mislead him/her and eventually end up with the wrong service or product. So, be relaxed, honest and ask whatever interests you, that's partly why this interview exists.
