Herring Calf:
They may call you or not call you at all.
Since you have first time ATPL passes and checkrides i think it's likely you will get a call.
They probably send and E-mail and ask for your CV, then a week later a call. They will just ask you if you passed everything at the first, your hours and invite you to an assessment a week after.
If you dont get an assessment they probably just send you an email or nothing at all. It can take a week or years.
Good luck and i wish you a successful assessment!
