Regarding the European market (My apologies to those not interested).
easyJet (Airbus) take on DEC every now and then, not often. They do hoover up MPL and full time cadet pilots from L3 and Oxford.
Ryanair (Boeing 737), they are on the charm offensive and hiring a lot of people.
Norwegian (Boeing etc), definitely hiring experienced pilots. Ratings not required, ideally, experience in wide bodies or command on 40+ tonne jets useful.
We're hiring, but you'll be an FO for 10 years.
(Large fractional bizjet operator)
Jet2 (Boeing 737 classic), hiring, usually quick commands for those with experience. Most folks I know do a year or two and jump to Virgin Atlantic if they can.
Vistajet, don't know, probably hiring.
BA etc, probably hiring.
Eurowings, hiring. (Must speak German)
Air France, hiring. (Must speak French)
Finnair, hiring (Must speak Finnish or Swedish).
UK regionals, various European regionals, hiring.
You'll need right of abode etc, EASA medical, exams and a licence... Budget a year to do it all. Unfortunately, in that time, it could all be over. Then the only folks hiring are easyJet and Ryanair and they'll take their cadets over experienced pilots.
Several airlines have recently gone bust, Air Berlin, Air Nikki, Monarch. Fortunately, the pilots were picked up by easyJet and Lufthansa. Alitalia's teetering on the edge again....
