There have been some changes to training recently and that's causing a lot of delays. Even if you've made it through the assessment centre, the wait for a start date could be long - a year or more. I'd tend to work on the assumption that if it happens, that's great, but don't rely on it happening in the near future. If you do end up with an earlier start date, then that's a bonus. It's really hard to be patient, but it's out of our control.
Cheers,
