Petroleum Engineer, Mechanical Engineer, or Aerospace Engineer?? Moderator's note: several related threads have been merged into one. Hi, I am trying to decide between these majors. I am going to be a Senior in High School next year. I live in Washington State. If I was a petroleum engineer, I would have to move to another state, right? How are the job opportunities for each of the 3? How stable are they? All these fields interest me and the pay in petroleum is really nice. I'm not too sure if I want to live in Texas thought. I'm not a big fan of that hot of weather. Which one should I choose and why? Thanks!
