For those of us who've applied in the latest (nov) campaign and haven't heard anything, I reckon its pretty safe to say a rejection email will be sent in the coming weeks.
The 4 week window of no reply and assuming unsuccessful is only applicable to those who did not recieve an invite to the online assesments. It's pretty clear in the email.
To those attending assesment days in the coming days/weeks, goodluck!
Hoperfully those of us still waiting to hear something after assesments will be put out of our misery soon!
