@ LorenzoH
maybe you are just arrived in aviation, if 23 is your age, I can tell you that everything is possible, permanent contract from the first day will be available for the direct entry with EZY FO
depending on the base chosen, and believe me, above everything they do what they need, trying to be polite with the old guys already in the company.
And the same for base, you will see that someone will arrive in the base you mentioned unavailable.
That's aviations
