I was about 15 minutes early. When I arrived I was immediately ushered into my interviewer's office, a few steps from the front door. He asked for a copy of my resume and just went down the list asking me about my experience. Felt like I articulated myself well and asked him strong questions. However, he seemed busy, 2 phone calls rang through while in his office, and didn't have much to ask. I was in and out in about 20 minutes.
