Yes. The Hanover Park Police Department hiring and background process is stringent and comprehensive. Police Officer candidates must pass a written exam, an oral interview, a polygraph exam, and a thorough background investigation. Upon receiving a conditional offer of employment, the candidate must complete a psychological examination and medical examination. A review of the candidate’s past work history, social media, arrest history, and many other areas are thoroughly reviewed. Candidates whose background investigations turned up evidence of any of those listed issues would be disqualified from the process.
