I applied through university. The process took 4 weeks. I interviewed at Citi
Interview
I had an on campus 30 min interview and a super day the next month. The super day is 3 45 min interviews in one day. They are behavioral and the interviewers just want to get to know you. They pay for your travel to the sight. They aren't trying to ask hard questions, they just want to see if you're a good fit for the company.
I had a behavioral with a current analyst, then a Superday with 3 members of the division. During the Superday, I was also assigned a case study to be conducted and presented live to the Superday interviewers.
Interview with HR and a current analyst (behavioral + CV). Another round where there was 2 interviews from people from the department and then a prresentation based on a document they present
I had 2 interviews. First one was general interview with 2 company employees, they asked about my experiences. Second one was interview with case study. with more specific technical questions.
