After reviewing the agency's job description, use the primary duties and responsibilities mentioned in the job description in your response. Focusing on using what the agency outlined in their job description shows the interviewer that you pay attention to detail and understand your responsibilities if hired.

You want to avoid describing a Fire Investigator's primary duties and responsibilities that do not apply to the job. For example, suppose you say a Fire Investigator's main responsibilities are to teach fire prevention measures and inspect businesses to ensure there are no fire hazards. In that case, you are not describing a Fire Investigator's responsibilities but rather a Fire Prevention Officer or Fire Inspector's duties.

"The main duties of a Fire Investigator are to collect and analyze evidence from the scenes of fires and explosions, interview witnesses, reconstruct fire scenes, send evidence to be analyzed, and determine the cause and origin of fires."
