I feel your pain my friend! Seriously. I am/was in the same boat for the last several years. Held numerous Type Ratings and about 4000 hours, but not current on any of my types. With one company, they wanted recency within 90 days and I was 94 days out, so that was a no-go.
I beat my head against a wall for a couple years trying to find a job. No luck. Experience is good if you are current. Remember you are only as good as your last LPC and that needs to be less than 3 months old for many operators.
I finally got out of the pilot seat because I could see where this train wreck of pilot supply and demand was headin'.
If you are interested to fly for an airline in Europe then you need to be a Direct Entry current Captain with 500 PIC in Type or a cadet. Unfortunately, the term "Experienced First Officer" is the green light for HR to trash your application.
You could apply as a cadet and simply say you have only 300 hours or so, but are eager to do whatever it takes to make the company profitable. Hide your experience because it counts against you these days. Remember, the decision makes see it as a simple equation: Experienced = Expensive. Obviously, that is ridiculous to you and I, but there is an element of truth to this statement.
Remember, there are many things that one can do besides fly an airplane. Pretty soon you will have to put food on the table. Only you can decide when you reach that point.
Best of luck!
