Citadel recruited for the FTAP program at my University. The first round interview consisted of a 30 minute behavioural and a 30 minute technical with a HR representative and then a FTAP alumni. The technical interview was fairly easy - mostly talked about your background in various fields and probed deeply in topics that the interviewer was interested in.
I was invited to a final round in Chicago. That was three technical interviews of 45 minutes each with a 15 minute behavioural with each interviewer. Similar format as the first round.
