NASA interview questions

I had two interviews. The first was a panel with 4 interviewers. They asked questions about my experience and why I though I was a good fit despite not having worked in a role like this one before (I was previously a software developer, this role was more similar to architect/DevOps/project management). They each took turns asking questions, and by the end of the interview I personally felt like I was perceived as not having enough experience and did not think that I would get another interview. I did get invited back though, and the second interview was a discussion with just the hiring manager. The night before the interview, she have me two real-world scenarios to talk through that would give a glimpse to how I would handle the different roles of the job. The whole process took a very long time. I followed up every week after the second interview for 6 weeks before I received an offer.
