Armstrong Fluid Technology Customer Service Manager interview questions

I was recruited for the position by a third party. When I arrived at the interview, the person the position reported to wasn't there. But they sent in a sub. Neither HR person nor the substitute person seemed to have read my resume. Company seems to be in upheaval. In hindsight, possibly they had already made a hiring decision (in which case, I wish they would have canceled the interview). HR person is hostile. Company has multiple mfg locations, so I asked which (or all) product lines are made at their facility. Answer snapped at me as if I'm stupid: "We make pumps" (They obviously make pumps, you can see as soon as you land on their web page.) She said this even though I'd mentioned earlier in the interview that I'd watched a few of their product launch webinars.
