Pilots joining easyJet are contracted to age 60.
Pilots who joined more than about 2 years ago are contracted to 65, and captains over 60 are limited by the rules in a few European states, and are therefore rostered accordingly.
There will probably be no change to this policy until over 60's have unlimited flying rights over Europe.
Therefore, unfortunately, anyone over about 57 or 58 has little chance of getting in. Unless, of course, requirements change, or you are type-rated, current, and a TRE (on type).
