Is this a sign to stay away from this agency?

I just had an interview earlier today where one of the interviewers was very sarcastic, and continuously interrupting me while I was answering their questions. I felt like they were talking down to me, which is crazy to me because I’ve had several interviews and never had an experience like this. Every interaction and interview I’ve had prior to this agency has been great.

The second interviewer was very nice and attentive to my answers and I felt confident when speaking with them.

I left there feeling like I wouldn’t be upset if they didn’t call me back because of how terrible the experience was. Is this a red flag to the culture at this agency?
