Hi Paula
I am not sure from your post as to whether you have had an assessment day or whether you have only just completed the online application form.
If it is the later, did you receive a confirmation from easyJet recruitment that the application had been received?
When I applied, I received an instant confirmation of receipt and an invititation to attend an interview around about 1 week later. When I attended an assessment day, I was telephoned the next day to say that they wanted me.
Good luck!
