No, you’re just misunderstanding it. I guess that usage is slightly rare, or perhaps regional, but it makes perfect sense to me. I bet either of these would sound OK to you: “I’ve gone for an interview”, “I’ve been to an interview”. They mean the same thing, and I can’t think of any reason using “been” and “for” together would be incorrect.
Yeah sure, nope. Has been what? Have been seen? Been invited, you are missing a few words.

Yes, she has. The grammar is correct. What is your query?
