Fwiw, every time I "meet the team after interviewing", it literally is just to meet the team. If there were any technical exercises involved, I'd expect an agenda or some kind of heads up. And it makes sense to wait for the technical evaluation before scheduling this sort of meeting, imo.

For bigger orgs, this is a chance to sanity check team fit and potentially re-route if longer-term interests align better with some other team. For startups, it can be more of a vibe check.
