Hi,
Essentially, the process for us was that we attended a 1/2 day at The Rivers near to the airport. We then signed in and met the other applicants before being split into groups with some attending a presentation or a group activity (we then swapped round). After both the group activity and presentation we were then interviewed.
Key points:
Be yourself/try to make yourself feel at ease with the other applicants as soon as you walk in/be prepared to ask any questions you may have/don't worry about the crew seat (it'll fit just about anyone!)/think about what you have done in the past when dealing with others - what problems you faced/how you managed them/turned things around.
Remember, they really do want you to do your best - plain and simple. There'll be no trick questions from the 2 interviewers (who will be taking lots of notes!). They really are decent people who will do their best to make you feel at ease.
Oh, the only downside is that when you start you will discover that LGW operates the 777 the same as LHR however, there are fewer crew on board meaning that you have to work even harder (no time to read OK/Hello/Daily Mail I'm afraid) and yes, the pay is absolutely appalling
unless you still live with mum and dad in which case you will be fine. As for commuting well yes, we get 'cheaper' flights but this is an extremely expensive option for someone on LGW terms and conditions. Also, there is a Gatwick BAA train discount card (for which you pay around a tenner) and this gives you 1/3 off fares to and from LGW.
Should you decide to go for the LHR Temp if it comes up, let me tell you that you will have a great time doing an LAX, YVR, SFO, MIA and wherever else. You will also earn far better money in the process - an average of £1900.00 per month as opposed to £1100.00 at LGW where you really do work very, very hard.
Whatever the case, do what is right for you at this moment in your life and things will work out for you.
All the best.
