My interview was set on 9:00am, and the account manager was arranged to walk me to the manager. The company is a branch in Chicago, nice environment. In the beginning I was a little bit nervous, later on it's better because the interview started immediately, as I was leading to the conference room and just seated myself.The interview lasted 1 hr, all questions are very practical, there was not a lot questions about concepts. well, for me it's a happy experience. I didn't get it, but they refer me to another company.
