First round was a phone interview with an HR person. He just asked about courses I am taking and my GPA so far. He explained about the position (travelling, training, etc.). He also asked about my salary expectation. I did not state any expectation so he basically told me what the salary range will be. I am not sure if should have negotiated a bit. At the end, he said he will schedule the second round interview soon. The next week I had the second interview with a director (on phone). He did not ask me technical questions. Most of the questions were behavioral or related to my past experience on the resume. It was really casual. I think there is suppose to be a third round as well but I have not been contacted by the HR yet.
