I don't know the engineering field. As a woman who entered law enforcement in 1984, and successfully made a career of it, I think the thing that helped me the most was to stop thinking of myself as "a woman in law enforcement," and simply see myself as " a police officer." When people need an officer, or an engineer, it does not matter if it is a man or a woman. What matters is their skillset. That being said, always be the best you can possibly be, because, unfortunately, any time a woman enters a nontraditional field, people will judge all women by that one person. They will say, "see, that's why women should not be cops." Don't be "that woman." We need you to lead the way!
Best of luck!
