1-on-1 phone interview with an analyst. Talks about background experience, technical questions (walk me through a DCF). It was a Quick 30 minutes. Followed up with final round interviews in Boston office. Case studies, very out-of-the-box questions, technical stuff, fit questions.. fast paced, quick thinking. Very hard to prepare for.. best advice is to read up investing books, blogs, and newspapers. You really have to go in with a good understanding of what makes a great company and be able to demonstrate your interest in the markets.
