Re: your first question, contact recruitment ASAP just in case they have forgotten about you
Regarding the hours, you will be rostered up to 130 hours per month for the first 6 months depending on where you are based, this will lead to you running out of hours. easyJet rostering staff are getting better with regards to hours (personally I was constantly running out of hours for around about 10 months and now I have a 50 hour buffer to play with) but you would need to be prepared for a reasonable period of high hours/no fly days.
BUT make sure you do contact recruitment ASAP regarding your contract!!
