Fairly quick interview, about 20 minutes, no silly games or anything more of a 1 to 1 chat. Arrive early as there are quite a few forms to complete, say 10 minutes. Mine was in a hotel on the seafront about 15 min from the airport.
They will need passport, photo's, and proof of experience etc. plus all bank details, uniform sizes. Needless to say I did not have all this with me, but they said I could complete it all later. I will say they seemed very nice, quite easy going, no pressure.
Seemed to know what they were looking for, as I am now waiting to hear myself, I do not know what !!!
Maybe see you in sunny Kent !
