Just had a phone screen, felt rushed, red flag?

I just had a phone screen with a recruiter, but it felt rushed. It was scheduled for 15 minutes. I was well prepared and answered the questions well, I think. But it felt like the recruiter wanted to end quickly. He asked the normal questions like tell me about yourself, what are you looking, salary expectations.

She called about few minutes late and the whole thing ended in 10 minutes.

I almost felt offended. Is this a red flag? What are your thoughts.

It was for an UX designer position.
