I have been working at Fried Frank Harris full-time (More than 3 years)
The willingness for change, the people, and the type of work.
Demanding environment but it forces you to have a high attention to detail and foresee business needs.
More than one interview. Time to talk with associate(s) as well as partner(s). Be prepared for phone interview then in person. Associates very casual. Resume and writing sample fair game.
