AFAIK, the cops don't call you. You have to show up on a Thursday, and the only person other than the clerk at the Records window that you interact with, is the photographer. There's no appointment, you show up, and they do the pix and prints first-come, first-served.
Except for when I moved to town, 25+ years ago, I have had one in-person chat with the LO, and that was when an old-style LTC was mis-typed, an I thanked him for taking care of it, speedily. I had one conversation by phone, when the LO wanted to know why I wanted an FID (renewal) when I had an LTC. "Because there's no law against it," was fine by him. "I was just trying to save you $100," he said....that's reasonable.
If your friend wants to know what's up....they should call, and ask. If you read the how-to in the link I posted above, there's nothing about an "interview."
YMMV...It's been a while, but my oldest needs to renew his FID, then apply for his LTC when he's old enough.
Crap...he used to be little.....
Pro tip....the FPD is NOT a fan of pork products:
