Total two rounds - 1st round is technical round, 2nd round is technical + coding.

Be prepared for coding round, prepare what you have mentioned in resume. All the best for the interview.

First round (1 hour) - Technical round: Questions related to projects on your resume: This is to gauge your practical experience and understanding of the projects you've worked on. Interrupts: Understanding of how interrupts work, their importance in real-time systems, and how to handle them. RTOS (Real-Time Operating System): Assessing your knowledge of thread synchronization, priority management, types of locks, memory management, deadlocks, and Inter-Process Communication (IPC). Debugging techniques: Your ability to identify and troubleshoot issues in code and systems. Linux environment experience: Cross-compilation, Yocto Project, Buildroot, and Linux command line familiarity.

Second round (2 hours) - Technical and coding: First half: Technical questions on projects and technical skills: Deeper exploration of your project experiences and understanding of technical concepts. Questions might cover handling multiple interrupts, differences between polling and interrupts, and deadlock resolution strategies. Second half: Coding challenges: Linked list: Assessing your ability to work with fundamental data structures. BST (Binary Search Tree): Testing your knowledge of tree data structures and basic operations like insertion and deletion. State machine: Evaluating your ability to design and implement complex logic using state machines.

Last 15 minutes: A chance for you to ask any questions you might have about the company, role, or interview process.
