Mechanical Engineering Technology Interview Questions

1,061 mechanical engineering technology interview questions shared by candidates

Q: You have 2 plates connected with a bolt, with a force applied to the plate horizontally. What is the primary failure mode? What is the equation for the stress? How can you reduce these failures? Q: In a simple RWD car, how much torque is required at the rear wheel? (they wanted a first-order approximation equation) Q: What are the modes of heat transfer? What factors govern the effectiveness of each method? Q: You have 2 dimensionally identical metal plates bonded together, 1 steel, 1 aluminum. They are heated together to the same temperature. What will happen? Which is in tension/compression? Q: Give an example of a time you showed extreme effort. Q: I have to write a letter to my CEO - how should I justify hiring you? Q: Have you received any awards that you are proud of? (in the context of an automotive cooling loop) Q: Give me a detailed explanation of what happens to one "particle" of heat in your system. Q: How did you determine your safety factor? Q: What assumptions did you make? Is there anything wrong with them? (in the context of a mechanical fixture) Q: How did you arrive on this shape? What are the alternatives? Q: How did you set up the FEA for this? Q: How did you choose your material? What were the tradeoffs?
