    Programs What is the likelihood of a physics major getting an engineering job?

    I’ve been told that physics majors are looked at favorably when applying for entry-level engineering jobs. Is this true? How qualified are they when compared to engineering majors? Are applied physics majors looked at any differently? Do employers care about an undergraduate thesis?
