Engineers are responsible for designing and building products. In an interview context, expect to be quizzed on your technical skills, and also evaluated for your ability to work as a part of a team to get things built. The specific questions you are asked will depend on what type of engineering position you are looking for. Try a specific engineering discipline, such as software engineer, electrical engineer, or mechanical engineer.
Have you played Borderlands? Seriously. Most of my interview was about gaming. Again, it was a personality test.
I was a little nervous and thought Borderlands was a software maker of a broad array of games. I didn't know it was a game in itself.
