Spectrum interview questions

In-person interview with the manager and some coworkers explaining the role. Everyone was very friendly and they described the role well. The majority of the interview was them describing what the team and what they needed, and only asked a few questions about background. They told me that they had a few technical questions but did not ask me any because they felt confident I knew enough based on my background. I did not get an offer, mainly based on the answer to one question they asked, described below.
