I got a teaching job once that was reposted. The first time around they had several hundred applicants, then the funding was held up, so they didn't interview or hire. When the funding came through, they reposted, mine was the first application in. They had to wait the required 3 days to see how many applications they would get, but I was the only person interviewed and I was hired on the spot.
This happened with my grandson, although it was not a professional job but retail. He decided to go see the manager, reiterate that he really wanted to work there and ask him what would make him change his mind and hire him. Turned out, the person who was hired had been late the first 2 days, and hadn't arrived yet that day. Manager said, "you were my second choice, you have a job if you will stay and work today. I need someone responsible with initiative."
