Yes,
OAT help you write your CV during First Officer Fundamentals and then you email them to careers who email them to BA.
If BA want to interview you, they'll contact you via email with all the instructions.
You'll do well at OAT, like i say don't rely on them to find you a job. The UK setup is outstanding, the US not so outstanding, but you'll have an awesome time out in the states:-)
