I wonder if this is what happened to me. I'm finishing up my PhD and despite being pretty set on going into academia, I applied to some industry jobs back in July that I was pretty uniquely qualified for based on my background and research topic (which is pretty niche). Never heard back. I have a nice postdoc lined up, so it's fine that I never heard back, but I was pretty surprised.

I recently checked and one of those job postings expired and was replaced with an equivalent posting in December. The other job posting (from a different company) is still open.
