Try to look for programs or mentorships related to engineering. Talk to your GC or other parents to see if they know any engineers that you can job shadow. The National Society of Black Engineers usually has a presence at most universities and some high schools. If your’re near a chapter maybe reach out to them?
Majoring in engineering and being an engineer aren’t always tied together. Plenty of people who major in engineering work in other fields like finance, computers, or become doctors or lawyers.
As a first-gen, URM if you decide to study engineering please take advantage of tutoring and career counseling. There are services at universities to help students who might not have attended a top high school. They help kids who might not be as well prepared for the rigors of engineering school.
That said, most of the people I know who became practicing engineers love to tinker, build, and break things. Many others I know went to med school, work in finance, or actuary work.
Good luck.
