Have to say the PPl skills test is there to make sure you are safe and not going to kill yourself ( or others ) when you go out flying on your own.
Obviously as a ppl you have minimal experience and are not expected to be able to deal with every situation 100% every time but you are able to make sensible and save decisions the majority of the time.
I wouldn't worry to much, just accept you failed it and learn from your mistakes, I guarentee you wont make them again.. Most employers will only be really interested in the IR, CPL and ATPL exam results and if they do ask you about the PPL and why you failed you just use that to your advantage and tell them how you learnt from it and as a result made you a better pilot.
Good luck anyway, use your experiences to your advantage..
