oil company internship

<p>I am going to be a junior mechanical engineering student at Lehigh University. I have a 3.6 GPA and am currently doing an internship at Air Products and Chemicals in Allentown, PA. I want to intern at a big oil company next summer, preferably Exxon or Chevron. Exxon recruits out of Lehigh, Chevron doesn't. What are my chances?</p>
