After receiving Bachelor of Science Degree in Electronics Engineering, I have number of years of experience in Engineering Services and Embedded Software Development. Now, I'm re-directing my career towards Embedded Hardware Design Engineering. I have not done any hardware design work, except in school many years ago. I don't know what tools are used by hardware designers, how to use them? Those Twenty page schematics are overwhelming. How can I ask good questions at the interview coming up in about a week? What are some of the good questions I can ask? If I get the job, how can I learn how existing circuits are working before designing new ones. How can I learn without getting help from others? Thanks,
