They have been interviewing, I do know that. I would call or email the HR department, it is rumored that apps and the pool are flushed ever year and re-filled. I don't mean to burst a bubble or spread a rumor, But I have heard this from more than one person that has spoken to out HR folks.

This is the place that does things exactly like that without telling perspective candidates, their belief is any unnecessary contact with you might obligate them to employ you someday, and that's a real sentiment.

Also know that they had a class of folks that had quit their jobs and left their employers only to be delayed because we were 'överstaffed" for a day.

IMHO it will not hurt you to call or email and verify if you are still in the pool or if you need to reapply. Do not assume they will tell you otherwise, call and find out. Maybe someone here that has a rec on file for someone could verify, but this is what I have heard.

Carry on......
