I am a foreigner student and have studied master and phd in Germany. My German is medium. During the interview, 1 hr and 2 technique managers sat together with me for 90 min. But only hr talked without any technique questions. The whole interview was kind of joke. hr was only interested in background check. She always wanted me to sell stories about how nice you are, what a good teamworker you can be. It was very stupid and unfair to determine a candidate only through 90 min's talk to judge his personality or background instead of professional skills. My feeling is Bosch is a very conservative company, especially suspicion of foreigners. Conclusion: Meaningless interview, I am looking for a job as eng not saler or hr. It seems they just want to take a chance to humiliate me.

2 Technical rounds 1 HR round. Some questions 1. What are the key differences between a Linear Regulator (like LDO) and a Switching Regulator? Expected: Discuss efficiency, heat dissipation, noise, and suitability for different loads. 2. Explain how you would validate the output of an LDO used in an automotive ECU. Expected: Mention input/output conditions, load testing, ripple measurement, and shutdown behavior. 3. What is the function of CAN_H and CAN_L in a CAN network, and how would you validate the signal quality? Expected: Use of oscilloscope, voltage levels, common issues like reflections, termination resistance. 4. What does UDS protocol (ISO 14229) mean and how is it relevant in ECU validation? Expected: Explain Diagnostic Session Control, DTCs, ECU Reset, and how these are validated. 5. How do you handle fault injection or error simulations during hardware validation? Expected: Techniques like signal disturbance, toggling pins, and simulating sensor failures. 6. How would you use CANalyzer or CANoe for communication testing and diagnostics? Expected: Explain logging, analyzing CAN frames, testing UDS services, simulation blocks, etc. 7. What precautions would you take while probing signals in a high-speed automotive communication circuit (like CAN or Ethernet)? Expected: Proper grounding, differential probing, avoiding signal loading, bandwidth consideration. 8. What is a pull-up/pull-down resistor and where have you used it in your test setups or circuits? Expected: Usage in default logic states, open-drain configurations, etc. 9. Describe your experience with End-of-Line (EOL) Testing – what parameters do you verify and how? Expected: Functional test flow, communication verification, power supply behavior, DTC triggering. 10. How do you debug an ECU that fails intermittently in production? Expected: Steps like reviewing logs, reproducing the issue under environmental conditions, analyzing CAN traces, using fault trees.
