They're looking for 737 DECs. Bases to be "oop north" to begin with - Doncaster, Manchester, Newcastle with southern bases to follow - Luton, Gatwick, Cardiff. Bournemouth is very popular with existing pilots so the chances of getting a Bournemouth basing are very slim.
You'd probably join at a northern base and move down south later if you bid for it. Base bid takes place twice a year.
They have run out of co-pilots to promote, it seems.
If you are not already 737-rated, they propose to reduce your salary by £2000 p.a. for 5 years as a "contribution to training costs". Courses at CTC or in Germany with Hapag-LLoyd.
They also want people with training experience as they wish to re-establish their own training set-up.
HTH,
