Scenario Questions
1. Scenario: A manufacturing company is trying to increase the efficiency of their factory floor by reducing energy consumption. As a Mechanical Engineer Intern, how would you approach this problem?
Candidate Answer: I would start by conducting an energy audit to pinpoint where energy is being wasted. From there, I would recommend implementing energy-efficient technologies and processes, such as upgrading factory equipment to more efficient models, implementing a building automation system, and optimizing HVAC systems.
2. Scenario: A company is developing a new product and needs to design a cost-effective manufacturing process. As a Mechanical Engineer Intern, how would you approach this project?
Candidate Answer: I would start by conducting a feasibility study to determine the most efficient and cost-effective manufacturing processes. From there, I would design and prototype the manufacturing processes, test them for efficiency and cost-effectiveness, and then make any necessary improvements.
3. Scenario: A company wants to reduce the weight of a product to increase fuel efficiency. As a Mechanical Engineer Intern, what steps would you take to achieve this goal?
Candidate Answer: I would conduct a design review and analysis to identify areas where weight can be reduced without compromising product strength or functionality. From there, I would recommend using lightweight materials, redesigning components to reduce weight, and implementing advanced manufacturing techniques to reduce material usage.
4. Scenario: A company needs to increase the throughput of their production line without compromising product quality. What strategies would you recommend as a Mechanical Engineer Intern?
Candidate Answer: I would recommend optimizing the production line layout to reduce material handling time, implementing automation and robotics to streamline production, and implementing statistical process control to identify and eliminate bottlenecks in the production process.
5. Scenario: A company is experiencing production issues with a product due to component failures. How would you approach this issue as a Mechanical Engineer Intern?
Candidate Answer: I would conduct a root cause analysis to determine the underlying issues causing the component failures. Once identified, I would recommend redesigning the faulty components, implementing better quality control processes, and testing the revised components to ensure they meet product specifications.
Sample numeric data question:
6. Scenario: A company is designing a mechanism that requires a certain amount of torque to operate effectively. If the mechanism has a radius of 2cm and requires 5N of force to operate, what is the required torque?
Candidate Answer: The required torque is 0.1 Nm. This can be calculated using the formula T = F x r, where T is torque, F is force, and r is radius. So, T = 5 N x 0.02 m = 0.1 Nm.

7. Scenario: Describe a project you worked on in school or a previous job that required you to use mechanical engineering skills. What were your responsibilities and what skills did you use?
Candidate Answer: In my previous job, I worked on designing an automated packaging machine that required fine-tuning components and programming control systems. My responsibilities included designing and prototyping the components, testing them to ensure functionality, and running simulations for control systems. I used skills such as CAD design, programming, and problem-solving to complete the project.
