They recruit in both the spring and fall. Here's the basic process: 1) Pass two online tests (1 hour) 2) On-campus behavioral interview (30 min) 3) If you get on-site, two more online tests (2 hours) 4) On-site superday (Mock trading and panel on Day 1, 1-on-1 on Day 2) 5) You hear back the week after. They like to hire smart math kids from Harvard with no trading experience. Even if you have a technical major, had relevant experience, and aced the interview, too bad. Go somewhere else where your background and interest are respected and desired.
