Embedded software engineers develop and maintain embedded systems, which may require advanced software skills and problem solving. In an embedded software engineer interview, the interviewer may ask questions that test your coding skills and experience. Expect to also discuss how you work with others, as the role may function within a team.
Technical Challenge: C-based Thread Scheduler Implementation During one of the interview rounds, I was tasked with implementing a thread scheduler in pure C. This challenge involved handling hardware timer interrupts and configuring the timer to manage thread execution. The focus was on demonstrating a deep understanding of low-level system programming and concurrent execution in a bare-metal or embedded context.
