Interview was very relaxed, one on one with a team supervisor and the hiring manager (although in my particular case, he was out for the day). Took place in a private conference room and lasted roughly 30 minutes. Primarily a conversation; wanted to figure out if I would fit into the group atmosphere. Also discussed proficiency in Microsoft Excel (this is imperative to the job) and general understanding of the financial industry as a whole (less imperative, but still important - you will be trained thoroughly on these subjects).
