Terri,
Your are certainly on the right track. I am glad that you are finding the information helpful. You might want to review the postings for the class as it will give you a variety of effective ways to interview. You will also find it helpful to write the questions down. Then you can really focus on the candidate and his/her response rather than having to think about what that next question will be. Also, it is important to ask open ended questions so that you really get a sense of your candidate and his/her ability to function well in the job. Interviewing is such an important responsibility and one which can impact the future. Taking the time to do it right will pay off many times over.
