Private Investigator Career Description

Do you like to find and analyze information?
Do you want a career collecting clues and uncovering facts?
Do you want a rewarding and challenging opportunity?

As a private investigator, you will be hired by a person or business to conduct an investigation. The private investigations are usually related to legal, financial or personal matters and involve collecting evidence. A typical day might include conducting computer searches, making telephone calls and working out in the field. You will routinely conduct interviews and do surveillance to gather information. 

In your career, you may choose to specialize in a specific area or provide a variety of investigative services, such as:

  • Executive, corporate or celebrity protection
  • Pre-employment verification
  • Infidelity cases
  • Individual background profiles
  • Identity theft
  • Child custody and protection cases
  • Missing persons cases
  • And more!

Many people bring previous experience to their private investigation career. This can include law enforcement, military or government experience, as well as finance, accounting and insurance work. This provides a perfect opportunity to apply previous work experience to a new career opportunity.
