Managers almost never want to be the one to do interviews, so it might feel like you're being pawned off onto someone. The questions are simple, but certain managers are more uppity and rude than others, who can be friendly and casual. They'll ask what you know about the company, past work experience, your hobbies, why you want to work for Culver's, the most complex being what makes Culver's stand out against its competitors, etc. It's very straightforward and quick.
