Please come and be nice to me. Just burbled, talked like I was about 5, incompetent, yikes.
I was terrible. Won't have got the job but it was for an internal promotion so now have to go on working alongside the lovely people who interviewed me who must now think I'm an arse. 
Literally the worst interview I've ever done. It was so bad I am sure I will be able to laugh about it one day - it would probably make a good comedy sketch of how not to behave in an interview!
If anyone has any words of comfort (or other awful interview stories) they want to share, that would be much appreciated...
