you can fly home that evening! once u finish in the afternoon- they advise you bu usually fone call bout 2-5days later!
i worked for easyjet for a year based @ edinburgh in scotland- absolutley loved my time there!
interview was fine- just relax & enjoy ur time- be confident talk 2 others- look enthusiastic & ask questions.
i now work for BA- well training & they had same sort of interview style.. good luck
