Gave my resume to a friend who worked there at a job fair held on campus. Received a phone call a week later and it was very behavioral. Second round was another phone interview - this one a mix between technical and behavioral. Third round (supposed to be the last round) consisted of 1 on 1 and 2 on 1 interviews as well as a written valuations test which tested you on formatting and finding grammatical mistakes on a page, DCF, and comps. I didn't hear back for about a month and decided to follow up and they asked me to come in to the office again for more interviews. This was again several rounds of 1 on 1 and 2 on 1 interviews which ranged from your standard technical questions and behavioral questions.
