Yes. Not only that, but they are extremely difficult jobs to get and generally go to the stop students from the top law schools.
There are career clerks (that's their permanent job) and clerks who cycle though out of law school for a few years. Getting one of those clerkships means you were a top student.
People fresh out of law school are the best at legal research because they just did lots of it.
