Viggi,
Gutted for you man. I know exactly how you feel. I was in those shoes 6 months ago when I failed but they gave me a second go. Did they offer you a second go or was it a flat no? Feedback given?
Dont worry about going back to drawing board - atleast you wont have a clean sheet start because your experience yesturday will stand you in good stead if you take onboard the advice.
Would you hazard a guess at what you thought went wrong. It might help others on here with their stage 3's coming up. If not I still have the notes from the email that gave generic feedback information if you want it.
P.S - Who interviewed you. Was it M.B or L.W?
Just wandering because M.B gave me phone call with feedback and it may be an idea to contact her. Although I didn't really want to speak to her the morning I got my fail result, her advice has proven to really help.
All the best
The Reverand
