I flew with check instructors, management, and FAA examiners that were supposedly 'tough to like.' Few of them were 'cake walks.' Many gave a VERY thorough ride. All were fair and good guys/gals. Don't believe the hype. Go out and fly like you are teaching the person in the other seat (you CFI applicants are). Relax, do your best, and have a little fun! Check pilots/examiners put their pants on the same way you do and really enjoy giving a SAT to a pilot to shows them a good ride.
