First part of the interview you meet with hardware engineering manager. He will ask you a few questions about your resume and ask you to explain about your past jobs/experience. They don't get too technically but its there are a few questions that they will ask that are key to your job, nothing too detailed but good to review. Usually the project manager will interview you next if its engineering job, they want to know if you will be a good fit in their team, standard personality questions. The whole interview process takes about 1-2 hours and they conclude with a company tour. As long as you know the general information about your position and your easy going it should be relatively easy.
