I have a question. If a hiring manager wants details on some of your projects, is that normal? (I've had some ask, but never this deep and over the phone)

Example: UI/API/ALGO how they were implemented, which parts you implemented, what was accomplished, pacific tools, why are you proud of those?

Looking for diversity in projects.

It's for a job interview. I thought it was weird, but Maybe I'm over thinking. Before I email them back, I wanna see what u guys/gals think.

BTW this email is from the HR Manager, not hiring manager, so I'm just going off her word. "She said, He said" sort of thing.

Thanks!
