Concur with the wisdom that they’ve hired you on paper if you get an interview invite, but you can invalidate that in person. Whatever the mistake, you have to own and at least outwardly use it to learn and improve.

A very good friend of mine got the 6 month answer and it was because they asked him about his speeding tickets. He had a pathological inability to accept that it’s a bad thing for him to get regular autograph requests from the highway patrol. He managed to own up and say something about working to improve when he returned 6 months later (with no new tickets during that period), and he was hired.
