Commiserations to all of you who have had your courses put on hold.
I was I this position a couple of years ago. It took a year before I got the call back, but it did come! We had to go through the selection procedure all over again, but the same people seemed to come through and were selected.
Having done it all again a second time, there was another delay of a few months, but the call up eventually came! We were told there may be another short interview but in fact this didn't happen.
I don't think anyone can predict what might happen in the coming months, but I will be having some contact with the training department in the next few days, so I'll try and find out what the current situation is.
It may be a couple of weeks before I reply as I'm away from home for a while, but I'll find a computer somewhere if there is any news.
Fingers crossed for you all.
