lookupMKULTRA's journey

I recently came across a job listing on Indeed that caught my interest, but shortly after I applied, the listing was taken down. I have an interview scheduled, and I'm feeling uncertain about whether I should still prepare for it or not. I wonder if this means the position has already been filled or if they just have enough candidates. I've heard from others that it's common for employers to remove listings once they feel they have enough applicants, but I still want to make the most of this opportunity. I'm considering reaching out through Indeed to clarify the situation, but I'm not sure if that's the right move. Any advice on how to handle this?
