As I understand it, it's well known that you will make Capt with some of the carriers (Easy/RyanAir) in less than 5yrs.
I can't comment on Ryanair.
The 5-year command thing at easyJet is a thing of the past. It happened during the period of fast expansion. Many people still believe this to the case. There is a pretty long list of command ready SFOs. If you join tomorrow, based on the current planned expansion rate I'd estimate you'd be waiting at least 8 years if not more.
