During the interview, the interviewer may ask you to help them resolve a specific issue. This can take the form of a simple question or they may present you with a use case and ask you to resolve it. Most of these questions should be easy to address since they correspond with the experience and knowledge gained in your previous roles. However, if you do run across one that you are unfamiliar with, rather than solve the case, describe the steps you would take to resolve it, including gathering the information you currently don't have.

"There are several ways you can reduce the power requirements of an embedded system. One is to put the system into sleep mode and periodically refresh your operating system. If the system is simple or static, you can pause some of the nonessential functions, such as the timer or clock, when it is not needed. While these power reductions will be minimal, they will help increase the efficiency of the entire system."
