Had a phone interview with one of their engineering managers and he explained that the position was more of a software engineer type. Thus I could not answer any of the technical questions, since my background was more on hardware or firmware type. He asked about structs, unions and linked list because I had C/C++ on my resume. Overall, it was an eye opener as now I know what topics I should learn more about when I practice C/C++ on my own over the summer.
