Bloody hell mate 'dress code' - jeans and a t-shirt.
What do you think old chum?
Prep, well I'd look at b737.org.co.uk for want of a better site.
I'd also gen up on most things jet orientated. Swept wings, coffin corner, Mcrit, High Bypass turbofans etc
Company history - check their website, know their fleet, expansion plans etc
Be prepared for the usual 'Where do you see yourself in 5 years' & 'describe a time when you dealt with a difficult situation with a successful outcome' type questions.
Above all, be prepared. Best of luck to you
