I've seen ATP applicants fail there.
Be current on instruments and multiengine procedures. You're there for a rating, not much else. So to get it done inthe alloted time, come prepared as they will teach the checkride. Do as you're told and you'll be fine. But as I said they do fail people, or at least that was my impression with the particular examiner they had over at Teterboro. Something the examiner stressed about one ATP applicant who failed his ride was that he didn't ride the rails down to the 1K marker.
