Apollo.io Business Operations Manager interview questions

I didn't make it to the interview process. I received a cold email from a supposed VP at Apollo, introducing me to a new role and asking if I'd be interested in applying. I was clearly in a cadence, and the recruiter followed up 2–3 times to get my attention (I hadn't checked this email in a while). Once I saw the thread, I responded with interest. They never responded. I followed up a couple of times — 0 response. I understand that the recruiter team may have not intended to include me in an outreach pool, and made a mistake. But I expect the decency of responding to my replies to let me know that the opportunity had closed. Bad vibes.
