Hi Francesco, have you been automatically emailed by easyJet?
Something like: 'Thank you for your application to easyJet for the position of Cabin Crew, which we have successfully received.Applications will be reviewed as soon as possible and we will contact you via email with the outcome of your application.'
If you got it then you just have to wait. It can take up to 15 days too and in some cases I know people has been waiting for over a month.
On the other hand they normally email back quickly in case of an unsuccessfull application. Hope it helps.
Regards
