I see a lot of ghost job interviews in tech. There are smaller startups, that post the job ad. I had interviewed for the company over and over again, always getting denied for one reason or another.
It is very common for the listing to be for some other position, “Senior Software, Fraud Prevention” or something, then during the interview it will be for their “Platform” team. If you ask about the team it doesn’t exist yet and they are always “slowly building it out”.
