Bob gave some AMAZING advice earlier that seems to have been overlooked.
GO TO THE INTERVIEW. If you're lucky enough to get one, take it. Go along and see what the company is all about. I work for BA at the moment and, to be honest, would be mad to leave what I currently enjoy for anything less than FSM/CSD/Whatever at Silverjet and that's why I don't work with the company.
I went for an interview back in Feb of 07 and was offered the job of Service Coordinator. It was a fairly difficult decision to make when I chose to turn the offer down, but if I hadn't been with BA, I wouldn't have thought twice.
The airline is run by a management team with passion for the company and a passion for service. The product offered onboard is amazing - the service offered on the ground is spectacular.
I fitted in with all of SJ's requirements for the Number One grade on their flights but they didn't even acknowledge that when I went for the interview. That annoyed me a little. The assumed I was applying for Main Crew and that was what put me off a bit.
Nevertheless, to make a decision based solely on what you read here would be shortsighted.
Get both sides of the argument for/against accepting a position with this company.
DO bear in mind, though, that with EOS' announcement that they will begin flying to DXB in direct competition with Silverjet, I fear Silverjet is facing some fairly difficult times ahead.
