Motivational Interviewing was developed to treat addictive behaviors, but has also been found to be effective in changing health behaviors such as physical activity (Hecht et al., 2005), dietary behaviors (Burke, Arkowitz, & Menchola, 2003), and obesity (Carels et al., 2007).

For the most part, interviewers ask situational questions to find out how you get along with others, how you handle stress, if you are easy to manage, and if you have the skills necessary to perform the job.
