Top 20 Interview Questions and Answers for Transdev PSV Electrician Role
1. Tell us about your experience with electric and hybrid vehicle systems.
Answer: I have hands-on experience maintaining and troubleshooting high-voltage systems in electric and hybrid vehicles, including battery packs, inverters, and regenerative braking systems. I’m certified in HV isolation procedures and trained in safe handling of lithium-ion components.
2. How do you ensure safety while working with high-voltage EV components?
Answer: I follow Lockout/Tagout (LOTO) protocols, wear appropriate PPE, and always double-check voltage isolation before commencing work. Safety is non-negotiable when dealing with electric systems.
3. What is a CAN-bus system, and how have you used it?
Answer: The CAN-bus system is a communication network that allows microcontrollers within the vehicle to communicate without a host computer. I use diagnostic tools like TEXA or Jaltest to read fault codes and monitor sensor data through the CAN-bus interface.
4. Describe a situation where you diagnosed a difficult electrical fault.
Answer: Once, I traced an intermittent power loss to a failing control module. The fault didn’t show up in basic diagnostics, but using an oscilloscope, I found voltage irregularities indicating a microcrack in the PCB.
5. How do you stay updated with new EV technology?
Answer: I regularly attend manufacturer training courses, subscribe to industry newsletters, and participate in forums like the IMI and EV Technician UK networks.
6. What’s your process for preventive maintenance on electric buses?
Answer: I begin with visual inspections, check connectors for corrosion, ensure firmware updates are current, test charging systems, and assess battery health using OEM diagnostic tools.
7. Can you explain the role of regenerative braking in EVs?
Answer: Regenerative braking converts kinetic energy into electrical energy during deceleration, which recharges the battery and reduces wear on brake components.
8. Have you worked with telematics or fleet monitoring systems?
Answer: Yes, I’ve worked with systems like Actia and ViriCiti to monitor vehicle health, battery usage trends, and performance diagnostics remotely.
9. What challenges do you anticipate with Transdev’s electric fleet?
Answer: Managing battery degradation over time, optimizing charging cycles, and integrating new models with evolving software will be key challenges—but ones I’m prepared for.
10. How do you prioritize tasks during breakdowns or emergencies?
Answer: I assess safety first, then use diagnostics to isolate the fault quickly. Communication with operations staff is essential to minimize vehicle downtime.
11. What electrical qualifications do you hold?
Answer: I have NVQ Level 3 in Vehicle Electrical Maintenance and have completed IMI Level 2 Award in Electric/Hybrid Vehicle System Repair and Replacement.
12. How comfortable are you working with schematics and wiring diagrams?
Answer: Very comfortable. I rely on OEM wiring diagrams to trace circuits, identify shorts or open circuits, and verify component connectivity.
13. How do you handle a situation where parts are unavailable for a repair?
Answer: I escalate the issue, propose temporary workarounds if safe and compliant, and keep detailed notes for when parts become available. Customer safety remains the top priority.
14. What are the most common faults you’ve seen in electric buses?
Answer: Issues with battery cooling systems, connector corrosion, firmware mismatches, and inverter failures are among the most common.
15. Describe your experience with charging infrastructure.
Answer: I’ve worked on troubleshooting DC fast chargers, verifying charge communication protocols, and ensuring proper grounding and power supply specs.
16. How do you manage documentation and compliance reporting?
Answer: I use digital platforms to log all repairs, parts usage, and inspections, ensuring compliance with DVSA and Transdev internal standards.
17. How would you explain a complex fault to someone without a technical background?
Answer: I use analogies and focus on the function and outcome, not the jargon. Clear communication builds trust with colleagues and passengers.
18. Have you ever trained or mentored junior electricians?
Answer: Yes, I enjoy mentoring. I guide apprentices through fault-finding logic, safe practices, and encourage ongoing learning.
19. What’s your approach to night or shift work?
Answer: I’m flexible and understand that reliability is crucial in transport. I manage rest effectively to stay alert and ensure safe, quality work.
20. Why do you want to work for Transdev?
Answer: Transdev is leading the green transport revolution. Being part of a forward-thinking, global organization that invests in cutting-edge technology aligns with both my skills and values.
