Had two phone interviews. The first one was a HR round. Not many behavioral questions in this round. Just asked to briefly tell about myself and told me to expect a call from hiring manager shortly. Second telephone interview was with my hiring manager. Tested basic knowledge in my area of expertise. Probed my awareness of the company and its products. Gave me a technical problem and asked to solve it while thinking out loud. I was extended an offer after they contacted my references. I had no on-site interview.
