500 hrs multi crew - means no Cherokees, Arrows, Senecas, 172's, 152's etc...but more likely ie. Saab340, Shorts360, Be1900 etc...real airliner environment, which means at least 6-12 months involvement in the industry flying IFR commercial routes.
I don't think many rookie pilots do have 500hrs on those, therefore It is reasonable, but It is not at the same time...
Yes, if you have no experience at all you still can go to easyjet via CTC.
For the rest, even with at least 500 hours Jar25 , easyjet has more applicants than available vacancies.
