Barclays interview questions

I've had 2 telephone interviews with Barlcays for different jobs. First one was very slick. Chap was obvioulsy used to doing them. He was professional and friendly. I was completely at my ease. He only threw me once when he asked me what was the thing about my job I enjoyed the most. I hate those generic question and went into woffle mode. The other interview was very vague with long silences. Neither were technical at all. The face to face was more technical. Only in that they slid a piece of A4 across the table with various queries on and wanted to know the result of one, fault with the other then a couple of questions about the difference between this and that. The rest of the interview was strictly competency based. At the end I asked them all about how they performance managed and didn't like what I heard. I think this came across an why I didn't get any further.
