The job description talked about managing containers at scale. Cool, I've been doing that for almost 10 years. But I've also been involved in much broader technical leadership and direction. I know that I have a lot to offer. First interview was with the hiring manager, the Director of Engineering. Next was a system design interview with a member of the team. Third was a cybersecurity interview. I felt like all went well. Then I got a message from the hiring manager saying that they were looking for someone with more experience with the specific piece of software they were using (doing the same things with different software didn't seem to count), and that "this is not a good place for learning." So I was out.
