I applied through college or university. The process took 1 day. I interviewed at Barclays in Jan 2012
Interview
Very basic interview, essentially a glorified "walk me through your resume." However, they are definitely looking for people with experience with Excel, accounting, and capital markets. It may seem very laid back, but don't be fooled. I had a 2:1 interview, and the two interviewers liked to play off of each other.
Interview questions [1]
Question 1
What experience do you have with the capital markets or individual stocks.
The process took 2 weeks. I interviewed at Barclays (San Francisco, CA) in Jun 2010
Interview
Interview consisted of two phone screens by members of the team. One was the project lead and the other was a senior engineer. The project lead threw me soft skill problems and the senior engineer asked me high level technical questions.
Afterwards, I was invited to the corporate headquarters for on site interviews. I performed a technical interview consisting of high level problems and programming with two members of the engineering team. Afterwards i spoke with the project lead once again.
