I applied through other source. I interviewed at Design Engineers
Interview
There is written test first on c programming, microcontroller and basics of electronics for 60 min then technical interview based on c language and microcontroller. Test and interview is easy.
While we at Design Engineers, PC of Iowa and Wisconsin appreciate the time you too to review our interview process, we do not currently hire Embedded Software Engineers, nor do we test for. You are perhaps reviewing a different company not located in the United States?
