I think you will find The Hill was referring to the direct entry side of things.
When they release the next round of interviews they email every person who is on the list waiting for interviews.
Its a 'first in best dressed' scenario, so you gotta be quick!!!!
If you miss out the first time they dont 'banish' you from the list, they'll just keep sending you emails with interview offers.
The Hill - mate get your phone set up so it beeps and rattles when you get an email. That way you can reply to an interview invite within minutes.
