I applied through college or university. I interviewed at Citi in Nov 2019
Interview
1 campus interview and a super day. Campus interview went great and the super day was harder. 4-5 30 minute interviews in which they ask you a variety of industry and personal questions. They took a very long time to reach back out which was annoying.
Round one was very chill, very conversational. Round two was three interviews lasting all about an hour and a half. Be prepared to speak on current news, Citi's financials etc.
