Embedded C is a programming language commonly used in the development of embedded systems. As with any programming language, it is important for candidates to have a strong understanding of the language and its concepts before entering an interview. To help you prepare, we have compiled a list of commonly asked embedded C interview questions. Whether you are a job seeker or an interviewer, these questions will provide valuable insights into a candidate’s knowledge and experience in embedded C programming.
