Obtain a copy of the job description from your local fire department before the interview or review the advertisement you responded to. That way, you can demonstrate your knowledge of how firefighters spend their time. For example, describe how some firefighters drive ladder and rescue trucks, while others drive tanker trucks with water for extinguishing fires. Indicate how you'd treat injured victims, write reports on fire incidents and educate the public, the U.S. Bureau of Labor Statistics suggests. The more knowledge you share, the more you'll stand out as a viable job candidate.
