Example of how to reach out and ask if you can shadow or interview someone:
Hello Mr. Engineer,
My name is Adam Sandler. I am a junior at Carrollton High School. I am looking into different careers and am very interested in learning more about being a civil engineer. My guidance counselor is encouraging us to shadow or interview people who are in the careers that we are considering in order to learn more. Would you be open to letting me shadow you or ask you a few questions about your job?
