I get the vibe that it's not autistic friendly, so I recommend masking as hard as you can. If you fall into being "too much" you'll feel like the interview went well, but that's not what they're looking for. Tone it down, focus on the topic at hand, and color inside the lines. If you're neurotypical ignore this feedback, it'll be an easy interview. But it's one of those interviews that's unintentionally a trap for the neurodivergent. Nothing against the people. It seems like a great company otherwise.
