Revolt Motors Vehicle Test Engineer Interview: Rounds, Questions and Preparation
For Vehicle Test Engineer roles at companies like Revolt Motors
What the job involves
A Vehicle Test Engineer at an EV company like Revolt Motors tests electric two-wheelers and their subsystems for performance, safety, durability, and reliability. The day-to-day work involves planning test schedules, instrumenting vehicles with sensors and data loggers, running on-road and lab tests, analyzing data, and reporting issues to design and validation teams. You will work closely with mechanical, electrical, and software teams to ensure the vehicle meets internal and regulatory standards before launch.
Role and Technical Knowledge
- 1
What are the key differences between testing an electric two-wheeler and a conventional ICE two-wheeler?
Highlight differences in powertrain (motor vs engine), energy source (battery vs fuel), absence of gears/clutch, regenerative braking, and additional tests like battery safety and thermal management.
- 2
Explain the function of a Battery Management System (BMS) and what parameters you would monitor during vehicle testing.
Cover cell voltage, current, temperature, state of charge (SoC), state of health (SoH), and how these affect performance and safety. Mention logging via CAN.
- 3
What is CAN bus and why is it important in EV testing?
Describe CAN as a communication protocol for electronic control units. Explain how it enables real-time data collection from motor controller, BMS, and other ECUs during tests.
- 4
What are some common tests performed on an electric vehicle's battery pack?
List tests like capacity, internal resistance, thermal runaway, vibration, shock, and ingress protection (IP) tests. Mention relevant standards like AIS 156.
Practical Scenarios and Problem Solving
- 5
During a road test, you notice the vehicle's range is significantly lower than expected. How would you investigate?
Outline a systematic approach: check tire pressure, riding style, ambient temperature, battery SoC, motor efficiency, and any fault codes. Suggest data logging and comparing with baseline.
- 6
You are testing a new motor controller and observe overheating under load. What steps would you take?
Mention checking cooling system, current limits, controller settings, and thermal sensors. Propose derating or design changes and re-testing.
- 7
How would you set up a test to measure the acceleration and top speed of an electric scooter?
Describe using GPS data logger or accelerometer, a flat test track, and consistent conditions. Mention safety gear and repeatability.
- 8
If a vehicle fails a braking test, what could be the possible causes and how would you diagnose them?
Consider brake pad wear, fluid levels (if hydraulic), regenerative braking interaction, tire grip, and ABS calibration. Suggest inspecting components and re-testing.
Behavioural and Situational Questions
- 9
Tell me about a time you worked in a team to solve a technical problem. What was your role?
Use STAR method: describe situation, task, action, and result. Emphasize collaboration and your specific contribution.
- 10
Describe a situation where you had to learn a new tool or technology quickly. How did you approach it?
Show adaptability and self-learning. Mention resources used and how you applied the new skill effectively.
- 11
How would you handle a disagreement with a senior engineer about a test result?
Focus on data-driven discussion, respect, and willingness to listen. Emphasize finding the root cause together.
- 12
Why do you want to work in the EV sector, and specifically in vehicle testing?
Connect personal interest in sustainable mobility with the hands-on, problem-solving nature of testing. Mention desire to contribute to reliable EV products.
HR and Company Fit
- 13
What do you know about our company and its products?
Research the company's EV models, technology, and market position. Mention specific features or recent developments.
- 14
Where do you see yourself in 3-5 years in this role?
Show ambition to grow into a senior test engineer or specialist role, contributing to advanced testing methodologies.
- 15
Are you willing to travel to test locations and work flexible hours when required?
Be honest and positive. Testing often involves field trips and odd hours; express willingness if true.
- 16
What are your salary expectations?
Research industry standards for freshers in EV testing. Provide a reasonable range and express flexibility based on overall compensation.
Ready to try it for real?
Take a timed test or talk through a mock interview for this role, then see your scores.
