Reached Final Manager Interview for Internship: What to expect??

Hi!

As the title suggests, I safely passed the HR and Technical interview and will have a final interview with the manager of the team. Doesn't seem as if he'll ask any leetcode questions or whatnot. I did receive some feedback from the recruiter that I should "take some time to prepare / do a bit of research on the company / product. The final interview is mainly for the manager to assess whether this's a mutual match". What kind of questions should I realistically expect and is this more of a formality if anything?

Sorry for the questions / rant
