Barcap's representatives are very nice in general. If you have questions don't hesitate to reach out to them. I contacted one of our alumini and he actually called back and gave me a mock interview before I went to the actual one. On the interview, I was asked to walk the interviewer through my resume first. He jumped in when he saw some interesting parts. He did a lot of talking along way too, so time passed really fast. Also asked why investment banking. Also a stock pitch and two simple brain teasers. I was pretty lucky to have an easy interviewer.

Overall a fairly standard IB interview. The first round is a good mix of behavoral and technical questions. Very friendly and encouraging envrioment really enjoyed getting to know my interviewer.
