100 Automotive Software Engineer Interview Questions & Answers

  1. What is your experience with AUTOSAR?

    • Answer: I have [Number] years of experience working with AUTOSAR, specifically with [mention specific modules like RTE, BSW, MCAL]. I'm familiar with the Classic AUTOSAR architecture and have [mention experience with Adaptive AUTOSAR if applicable]. I understand the benefits of using AUTOSAR, such as improved reusability, scalability, and standardization. I have experience in [mention specific tasks like configuration, integration, or development within the AUTOSAR framework].

  2. Explain the difference between Classic AUTOSAR and Adaptive AUTOSAR.

    • Answer: Classic AUTOSAR is designed for applications requiring predictable real-time behavior and deterministic execution, typically found in less complex ECUs. It uses a static configuration and is less flexible. Adaptive AUTOSAR, on the other hand, is built on a service-oriented architecture using POSIX and is more suited for complex, high-performance applications requiring dynamic updates and communication. It's more flexible and adaptable to changing requirements.

  3. Describe your experience with embedded C programming.

    • Answer: I have extensive experience in embedded C programming, having used it to develop [mention specific projects or applications]. I'm proficient in memory management techniques, working with pointers, and handling interrupts. My experience includes [mention specific aspects like RTOS integration, working with peripherals, and using debugging tools].

  4. What are your experiences with different Real-Time Operating Systems (RTOS)?

    • Answer: I have worked with [list RTOS, e.g., QNX, FreeRTOS, VxWorks]. My experience includes tasks like scheduling, task synchronization, inter-process communication, and memory management within these RTOS environments. I understand the importance of real-time constraints and have implemented solutions to meet critical timing requirements.

  5. How familiar are you with CAN, LIN, and Ethernet communication protocols?

    • Answer: I am proficient in CAN, LIN, and Ethernet communication protocols. I have experience in [mention specific tasks like configuring CAN controllers, developing LIN applications, implementing Ethernet communication stacks, and troubleshooting network issues]. I understand the differences in their performance characteristics and appropriate use cases within automotive systems.

  6. Explain your understanding of software development methodologies (e.g., Agile, Waterfall).

    • Answer: I have experience with both Agile and Waterfall methodologies. In Agile, I'm familiar with Scrum and Kanban, and understand the importance of iterative development, continuous integration, and close collaboration. In Waterfall, I understand the sequential nature of the process and the importance of thorough upfront planning. My preference depends on the project's needs and complexity; [Explain which you prefer and why].

  7. How do you ensure the safety and security of automotive software?

    • Answer: Ensuring safety and security is paramount. I follow coding guidelines like MISRA C, use static and dynamic analysis tools to detect potential vulnerabilities, and participate in code reviews. I'm familiar with security best practices, such as secure coding techniques, authentication and authorization mechanisms, and implementing intrusion detection systems. Following established safety standards like ISO 26262 is crucial in my approach.

  8. Describe your experience with debugging embedded systems.

    • Answer: Debugging embedded systems requires a systematic approach. I use various techniques, including JTAG debugging, logic analyzers, oscilloscopes, and print statements for basic debugging. I’m proficient in using debuggers like [mention specific debuggers] and am comfortable analyzing memory dumps and core files to identify the root cause of software failures. I use a combination of top-down and bottom-up approaches depending on the complexity of the issue.
