Oooo so glad that's over!
For anyone else doing their AC2 soon my opinion is as follows:
The interview wasn't as bad as I thought it would be. quite straightforward.
Standard tell us about yourself question.
Competency ones, definitely have two answer options for each of the four subjects.
Pick the one that fits their question the best. (mould it to the specifics of the question if you can)
Practise the rVce if possible, it is a little tricky to get all the relevant info down in the time you have, it's a fair bit of information.
Also when converting your notes into what you're going to say, use shorthand or bullet points as the 5 mins goes really quick!
(I didn't quite finish and had to wing it at the end from my notes)
Speak kinda slowly, (and clearly) so you don't mess up lol
Now the dreaded wait begins!! argh!
Edit - DARK CHOC
Thanks for asking, I think it went quite well, couple of bits could have been smoother but overall I'd be happy with it if it was a normal interview, Obviously though for this one the competition is really tough! so we will see!
