FAA application question

I recently applied for a job with the FAA, the application closes on February 22nd. Will I only hear back after it closes? It’s been open for like a year so it seems weird to only reply after the close date for those that applied months ago? This is my first time applying for a Job with USAjobs so any insight would be helpful. Also- Is anyone in here a ACSI for the FAA? Or know anyone who is?
