Was asking at the careers centre in HQ the other day for a friend, the girl on the desk told me that there is currently a 12 month 'waiting period' for anyone working for QR who wants to come work for EK. When I asked her if it was only for the job role in question, she said no, it applies for any job in EK. This was maybe 2-3 months ago, so I don't think it's just a rumour unfortunately.
