@alex: I wouldn't give up this early, first of all it has only been a week since the skills assessment. Stage 3 is continuing as from next Monday so if OAA/Easyjet won't meet their quotas for applicant entries, I presume OAA will send more positive emails
I have been told last week by an OAA skills training guy, that an email will be sent irrelevant being positive or negative reply. So sit tight and try to forget about it for a while
