I have run into this in the past. Usually a Technical Lead or Director of Engineering is grumpy, gives me a very perfunctory 5-minute interview, has clearly already made up their mind. It was just a waste of time for me and their company.
Yeah, I interviewed someone over 60 a few months ago and myself and the other engineers who interviewed were all intimidated. It was fine once we were in the interview room but reading the resume scared everyone a little.
