I haven't heard anything back yet - I ended up having to hand deliver my application form on the very deadline as Royal "I can't deliver anything within ten years" Mail decided to lose my original application form.
Incidentally, I phoned Royal Mail up and said my letter had disappeared, and the kind lady informed me that "royal mail doesn't classify a first class letter as 'lost' until 14 days". 14 days to deliver a letter?!?!?!?!
Anyway, I thought they were writing to successful candidates in early May?
No news is good news I guess...fingers crossed!
