Being the neurotic law student you are, you've probably already started thinking about OCI even though it is still July. Considering the state of the legal market in the past few years, that's a good thing. Also given the market, we OCI starts up, we would suggest applying to as many law firms as the OCI process will allow. Then, after you have all your offers (and hopefully you will have at least one, and even better, a few to choose from), you'll need to decide which firm is right for you. And, just how exactly are you supposed to do that?
While there are many factors that go into deciding which firm's offer you should accept such as niche practices, or industry-specific standing, one of the main factors that will determine how happy and how far you will get at the firm may be one of the most important factors: firm culture.
