r22
Not a lot of margin in the R22, and the examiner probably let things get to the limit of his/her comfort zone before getting the rrpm etc, under control. In the real thing, you won't have the luxury of an announcement before the emergency.
As someone mentioned, you need thick skin to be a pilot....no matter how high you climb on the ladder, there is always someone to check you out...and your reputation is only as good as your last flight.
The trip report or 'hate sheet' tends to not leave much room for complimentary comments...more about the things you did wrong, or need to tidy up. That's the game.
Keep plugging away, but don't let the failures get you down. Work out where you went wrong, and approach the next check ride with a positive attitude.
Happy landings...
