Interview
I applied online then had a phone interview and was asked to attend the Super Day in NY. I had three back to back interviews, 30 min each. For the most part, the interviews were behavioral - asking how you perform in team settings. They were impressed if you knew current events about the company and could elaborate about certain financial concepts. Got an offer within two weeks.
