Tesla Thermal Test Engineer interview questions

Had a phone screen, then an interview with one of the engineers on the team. Was asked about how familiar I was with the cooling system in their vehicles. I said no and asked if he could explain it to me. He proceeded to laugh and tell me to just look it up online after. I've had other interviews at Tesla that were fine, but this one in particular, the engineer came off as condescending, making this a negative experience for me.
