Unacceptable behavior for an interviewer. Ironically, that person did you a solid by showing you this wasn't the company you want to work at without already starting there and investing even more time with them. Imagine finding this out after you quit a current job, and low and behold, this guy is your new boss.
You are the candidate and hold equal power. In the thought process you had "I think I should terminate this interview." If it ever gets to a point you are uncomfortable due to rudeness, leave. Sure, in a big faang world you may never have interaction with that person, but them being on the panel has a chance they would be your boss, peer, or in your org some way.
Toxic people can ruin what would otherwise be good careers. Alternatively, this can also be a huge indicator a company tolerates and promotes this behavior. To me, while it's possible, that this was a once and rare thing that only this person has done... Screw betting my career on the least likely possibility.
