Good solid company, reasonable benefits (over and above getting paid for flying!).
More likely to start on the King Air. Interview fairly standard, no psychometric stuff, no tricks. Group session first, then one-one interviews. Just be honest, and be prepared for some ATPL type questions and why you want the job.
You'll get a good overview of the company from them on the day in the group session.
Falcons seem to attract ex-military types (which makes sense due to their type of flying). Right seat is attainable for low timers but preference for upgrading may go to guys having flown the King Air.
Teesside flies for the RAF and Bournemouth for the Navy (primarily).
Cheers.
