About Embedded Interview Questions
A curated collection of embedded systems interview questions focused on operating system concepts. Covers topics such as inheritance, multithreading, watchdog timers, virtual memory, priority inversion, reentrancy, spinlocks, atomic operations, concurrency vs parallelism, thread vs process, mutexes and semaphores, thrashing, and paging. Sourced from the nhivp/Awesome-Embedded repository, this resource is ideal for candidates preparing for embedded software engineering roles.
