Former federal law clerks are often highly sought after by large law firms. Firms believe that such individuals have excellent legal research and writing skills, and a strong command of the Federal Rules of Civil Procedure and Federal Rules of Criminal Procedure. Firms are even more interested in a former law clerk if the firm generally appears before the clerk's former judge. The interest in former law clerks is seen by the fact that most large firms have a special hiring process for former clerks, and often pay such individuals large signing bonuses.
