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.
