Same torturous experience - only to end up on £15k less than your colleagues up the road on the Golden Runways - if you're successful, that is. You could eventually find yourself up at Heathrow by choice after a few years and ultimately you're a British Airways pilot hence the same assessment process.
That said, you'll be assessed by EF staff and they're an extremely friendly bunch, so the experience will be slightly more palatable.
Good luck. I Think there's been some subtle changes to the process but somebody who's been through it recently will hopefully post the details.
