simple conversation on why you want the job and how you handle people. They hiring manager just chatted about my goals and interest. As long as your can talk professionally to people, you should be fine.

I saw job posted on Craigslist, and applied. About a week later I got a call for an interview. The office manager calling asked a few screening questions, mostly to gauge how you sounded on the phone, as the job involves cold-calling. The interview questions were very easy, no trick questions, and they were largely behaviorally based questions.
