I assume that does not include scenarios where the large company interview claims they can't answer questions about a specific job until much later after a "team matching" step.
Sure. Obviously there's exceptions, and I mostly haven't worked anywhere where that's been an issue, but you also know what you're in for if you're interviewing somewhere that size. It's a very different process.
That said, I've regularly done interviews from both sides where I wasn't talking with someone who would be anywhere close to my role/team, and there's still plenty to ask there. At worst, you'll learn some about a different part of the organization, and maybe get some interesting contrast to other people you talk to later.
Even finding out what things are and aren't the same across the whole company can be interesting. Does vacation policy vary by team? Their use of various tools? Their work/ticket management process?
