The interview process was:

• A standard resume review and initial screening for minimum requirements.
• A detailed phone interview with several stages of technical questions.
• Four live interviews, including lunch and a site tour, to keep you interested in working for them.

Most of the questions were technical with objective answers. This is expected for an engineering position, and they were all fairly straightforward.

The most difficult portion of the interview was the open-ended, scenario-based questions. Basically, these give the employer a chance to see how effective your problem-solving skills are.

What really makes this difficult is that there is no "right" answer, but there are a lot of "wrong" answers. In short, be prepared to think about the questions asked; memorizing trivia will not help.
