Investigators are professionals who specialize in gathering information and evidence for a variety of purposes. They may work for private investigation firms, law enforcement agencies, or as independent contractors. The work of investigators involves conducting research, analyzing data, and interviewing witnesses to uncover information that can be used in legal proceedings, insurance claims, or other types of investigations. Investigators must be skilled in critical thinking, problem-solving, and communication, as well as have a strong attention to detail and the ability to work independently.
