Frankly forget the 767. We only have three and that's due to drop to two next year thanks to European/Virgin/Monarch/Britania selling cheaper longhaul seats than we can.
As for what the company is like to work for then you will find a reasonable flight deck management, who's hearts are essentially in the right place, being squeezed by the balls by the board of First Choice through their lackies to reduce costs and safety to the point where the pilots and cabin crew are now so demoralised that any attempt to 'get the job done' comes from fear of retribution from above or a mild sense of duty to the passengers rather than company good will.
The union (BALPA) are powerless and the company know it. The crews are great, but the work is hard. Expect no personal life May to November, but if it's jet time you want, then it's an opportunity, but remember you will be selling yourself and all future potential jet pilots short by agreeing to this 'hire 'em cheap' ploy.
