My mate applied earlier and got this response within a couple of hours:
We're pleased to let you know that we have now received your completed your online assessment(s).
Whilst we endeavor to progress everyone to the next stage of the process, this is not always possible when we are dealing with high volumes of applications. On occasions like this and in the interests of fairness, we will only be able to progress those that fall within the top scoring bracket.
Due to the volume of applications we receive for these positions, it can take some time for us to provide you with an update. We will be back in touch at the earliest opportunity.
