@bendmeoverbackwards - it was a short interview, they were running late so there was no chat, they asked her mainly about her submitted work. Long story, but she hadn't been happy with what she had to submit for that subject. She came out feeling ok but not really knowing how she'd done.
The thing she agonised over afterwards, was at the end of one of her interviews, (she was going for joint hons so had interviews for both subjects) they asked her if she would consider single hons. She thought this was a trick q to see if she was serious about her subject choices and said no. Then afterwards realised that they can offer places for the individual subjects to students who have interviewed for joints. Arghh. Fortunately it didn't matter in the end.
