Pros
It's a good thing to put on your resume. You may occasionally get an opportunity to go on a shoot, but only one intern is allowed on each shoot and if you're an intern, it's between you and the twenty other interns so your chances of going on a shoot are one in twenty.
Cons
Every intern just does logging and occasionally goes on runs. You just sit at your computer all day logging. No one looks from their computer or talks to you. And there are at least 6 other interns there everyday doing the exact same thing. I'm pretty sure they'll hire anyone regardless of if you're qualified.
