You get a mix of your own small cases, where you learn by fire, and at the same time being a team member on bigger cases with partners. I did my first opening statement at a trial the very next month. Associates feel that they can handle early responsibility both because of the support and feedback they get, and the firm's formal training programs. It's taught by partners, and they tailor it to show you what works for you personally. There's nothing cookie-cutter about it.
Associates find their informal feedback tremendously valuable.
They turn everything you write into a valuable learning experience. A lot of firms will bring you in for three or four or five years, use you, and then spit you out. That's fine, as long as you know what you're getting into. But a lot of the time it's not obvious. You're going to get a lot of experience here.
