<p>I agree with you that it will be hard for you to transition to a national firm unless perhaps a partner from your firm is willing to make the connections for you. I know several 3rd-5th year associates who successfully transitioned laterally to other biglaw firms but many are reluctant to hire someone so close to partnership track. Don’t despair, concentrate on looking at smaller regional firms that will value your biglaw experience especially if you are willing to relocate outside the NE.
Besides your law school career center, take a look at job postings at Penn too. Good luck.</p>
