Top Interview Questions on Interrupt Service Routine (ISR) | Master Embedded Interview Guide (2026)
Interview Questions on Interrupt Service Routine : When preparing for embedded systems interviews, one of the most important topics is the Interrupt Service Routine (ISR). Recruiters often ask questions on ISR because it is a core concept in microcontrollers, operating systems, and real-time systems. In this guide, we’ll go through commonly asked ISR interview questions,…

What Are the Typical Synchronization Mechanisms Used in an RTOS? | RTOS Interview Question (2026)
Typical synchronization mechanisms used in an RTOS (Real-Time Operating System) are techniques that manage the coordination and safe sharing of resources among multiple tasks running concurrently. These mechanisms—such as semaphores, mutexes, event flags, message queues, mailboxes, and barriers—help prevent race conditions, ensure mutual exclusion, and maintain deterministic behavior in time-critical applications. By enabling controlled access…
