I recently appeared for an interview for the position of Embedded Software Engineer. The interview was highly technical and focused on both theoretical knowledge and practical experience with embedded systems. The interviewer asked about my familiarity with microcontrollers, real-time operating systems (RTOS), and low-level programming, especially in C and C++.
Can you explain the differences between microcontrollers and microprocessors?
How do you optimize code for memory-constrained embedded systems?
Have you worked with any RTOS? Can you explain task scheduling and synchronization mechanisms?
What tools or debuggers do you commonly use during embedded development?
This experience was shared anonymously to help others prepare for their interviews.
