I interviewed the technology summer internship first round in London in the end of December. It lasts for 35-40 minutes with two business people from this particular division, one is associate and another one is AVP. It's all about competency questions, and even not going through CV. They are quite nice and all questions were quite conversational. I thought I performed quite well in the interview, but still got rejection.

This was the worst interview experience I have ever had. I had 3 back to back interviews with 3 leads from different divisions. First of all, the interviewers seem uninterested and inward. Questions were vague and little had to do with accessing any technical or personal skills. I even had one interviewer who had to pause the interview 3 to pick up phone calls.
