Also, feel free to PM me if you have any questions about the conference.
Last year, I applied to 8 public interest employers (legal aid, PD offices, private civil rights firms) for interviews at the career fair. I received 5 interviews from legal aid offices and PD offices. None from civil rights firms.
Another piece of information: some employers may not follow up after the EJW fair until fairly late. For instance, I didn't hear back from two organizations until January, 3 months after the conference.
