Sorry unable to shed light on interview day as I was taken on as a temp last year, and interview was one day.
EuroGatwick is a different contract to Eurofleet at LHR. Eurofleet have more days off in a month, allowances are paid as either Bfast, Lunch and Dinner while EuroGatwick paid by the hour for there allowances. Transfer between the two usually 5 years, but not automatic. EuroGatwick is all 737-400 ops. They work harder as well.
Its basically ex Dan air.
Crews are younger and they tend to have fun!
