Interesting how people's perspectives differ.
I watched the interview and thought she looked tired, yes; she'd been up til probably the early hours from the premiere or whatever it was the night before and then they had her on early in the morning - but I have a lot of sympathy with that, I'm not a "morning person" either.
Getting her name wrong from the off is just hopeless. At least find out who you're talking to! Poor professionalism point 1.
They talked over her - could be a time delay on the link up but it's rude and they made no apology - poor professionalism point 2.
She was sarcastic - trying to be funny but in a deadpan way that didn't quite go over properly - don't think that counts as a lack of professionalism, more immaturity.
They asked her a godawful stupid convoluted question - she was taken aback because it took some thinking about and was pretty dim as questions go, IMO.
Then they started to bite - and she wasn't impressed but still tried to answer.
The ONLY mitigating point in the interview is that one of the anchors seemed to realise that she was being sarcastic, but he got shouted down by the other 2, especially the female anchor, who was determined that Cara was just "in a mood", and the bitching was entirely unprofessional.
Well I don't think anyone came out of it covered in glory, but my preference goes to the actress in terms of who handled it better, and the anchors were ruder than she was.
