The interviewer wants to hear that you are passionate about a career as a parole officer. Take this opportunity to share with the interviewer if a specific life event leads you to a career as a parole officer.
"When I was young, a good friend of mine experienced a life event because of a criminal and I saw first hand how it impacted their lives and the lives of their family. I made the decision then and am carrying it out now to take a career where I could be responsible for monitoring recently released criminal offenders to ensure they are integrating back into life after serving their time. I take great pride in my work and am proud to be interviewing for this opportunity."
