Citi group interview - technical interview


I have an interview with citi group. i’m a newly qualified accountant. The role is product controller.

Could anyone give me ideas of what they’ll ask in the technical interview? i’m a bit concerned about it and not sur ehow much depth they’ll go into

Also if anyone has worked there i would like to learn more about their culture. what type of place is it to work for? do ppl generally enjoy it? are there any better investment banks to work for?
