I sent them an email last week asking about the status of my application.
Got this reply this morning.
Dear ****,
Thank you for your email.
We are still reviewing all applications for the First Officer recruitment campaign. Due to the unprecedented volume of applications the reviewing process will take a number of weeks.
Thank you for your patience. We will be in contact with all candidates in due course.
Best regards,
The Aer Lingus Recruitment Team
So maybe they're inviting some candidates maybe not but this is my current situation.
