🔧 Bosch Interview Experience

Role: Embedded Software Engineer
Mode: Virtual (MS Teams)
Rounds: 2 Technical + 1 Managerial + 1 HR

---⬅️ Back

🧪 Technical Round 1: Embedded Concepts & Protocols

Focus Areas: - Bitwise operations - Embedded C and memory types - HIL (Hardware-in-the-Loop) Testing - Communication protocols: CAN, SPI, LIN - MISRA guidelines

Sample Questions: 1. Explain how you would use bitwise operations to: - Set a specific bit in a register - Clear a bit - Toggle a bit - Check if a bit is set

  1. What is the use of volatile keyword in embedded C?

  2. How do you ensure memory safety in embedded programming?

  3. Explain the CAN protocol and the role of each field in the CAN frame.

  4. What are the different types of memories in microcontrollers (RAM, Flash, EEPROM)?

💡 Technical Round 2: HIL Testing + Model-Based Design

Focus Areas: - HIL test bench setup - Vector tools (CANoe, CANalyzer) - Integration testing at ECU level - Usage of MATLAB/Simulink & Stateflow - Fault injection and diagnostic simulation

Sample Questions: 1. Explain your experience with HIL testing. What tools did you use?

  1. Describe a case where you wrote a test case for an input fault condition.

  2. How do you simulate sensor inputs in HIL systems?

  3. What are the different types of Stateflow charts? Why would you use Mealy vs. Moore?

  4. How do you handle calibration and diagnostics in a model-based environment?

🧩 Managerial Round

Topics: - Team collaboration & Jira workflows - Deadline-based deliveries - Agile experience - Ownership of deliverables - Handling last-minute spec changes

💬 HR Round
