It was a nice interview experience. I didn't feel like the interviewer was grilling me. All questions were very relevant to the position open, and they simply wanted to find out the level of experience I had with several job requirements. The areas they wanted to know if I had experience with was AutoCAD, cost estimation. The interviewer I spoke with was very friendly and helpful. He even gave me a feedback when I requested why they decided not to advance my application, and I understand some other applicant had more direct work experience in the areas they were looking for.
