Interviewer: Can you give an example of a time when you came up with a creative solution to a problem?

Candidate: I once had a problem with a machine that continuously malfunctioned. My team and I studied the machine and then designed and fabricated new parts and mechanical components to replace the faulty ones. Our solution worked well, and we implemented it across other machines in the same category.

Interviewer: What software or tools do you use for design or maintenance work?

Candidate: I have experience with computer-aided design software (CAD), computer-aided manufacturing software (CAM) and computerized maintenance management software (CMMS). I am also proficient in using various hand tools.

Interviewer: How do you manage your time when working on a large project?

Candidate: I break the project into small and manageable parts, create a time frame, and designate specific deadlines for each part. I continuously review the progress made, making sure to stay goal-oriented, and updating stakeholders accordingly.

Candidate: I am driven by my passion for the field and a desire to deliver excellent results. I see each project as an opportunity to learn new things and improve my skills, and that motivates me to perform my best.

Scenario Questions

1. Scenario: A machine is producing goods at a slower rate than expected. How would you diagnose the issue?

Candidate Answer: First, I would check the machine's manual or run a diagnostic test to see if there are any error codes or reported issues. Then, I would inspect the machine for any physical damage or wear and tear on its parts. If there are no visible issues, I would check the machine's settings and adjust them accordingly. If none of these solutions work, I would consult with colleagues or superiors for further assistance.

2. Scenario: You are tasked with installing a new hydraulic system in a piece of machinery. How would you approach this task?

Candidate Answer: First, I would gather all necessary tools and equipment, as well as the hydraulic system user manual. I would then carefully remove any existing hydraulic system components and install the new components according to the manual's instructions. Once the system is in place, I would conduct an initial test to ensure there are no leaks or issues with the system's performance.

3. Scenario: You are asked to repair a gear on a large industrial machine. What steps would you take to approach this task?

Candidate Answer: I would first identify the damaged gear and consult the machine's manual to determine how and where the gear needs to be repaired. Then, I would disassemble the machine to reach the damaged gear, being sure to follow proper safety protocols. Once the gear is accessible, I would carefully remove the damaged gear and replace it with a new one. After reassembling the machine, I would conduct a test to ensure that the gear is properly installed and functioning.

4. Scenario: You are tasked with diagnosing an issue with a conveyor belt system that has stopped working. What steps would you take to diagnose and repair the issue?

Candidate Answer: First, I would visually inspect the conveyor belt system to see if I can detect any visible issues. I would then run a diagnostic test on the conveyor belt system to see if there are any error codes or issues that have been reported. If there are no visible issues and the diagnostic test comes back clear, I would then inspect the conveyor belt system's motor and gear system to determine if there are any issues there. Once I've identified the issue, I would take the necessary steps to repair or replace the damaged components.

5. Scenario: You are in charge of maintaining a fleet of vehicles used for transporting goods. How do you ensure that these vehicles are always in optimal condition?

Candidate Answer: I would establish a regular maintenance schedule, where each vehicle is inspected and maintained at regular intervals. This would include checking the vehicle's fluid levels, brakes, tires, lights, and other essential components. I would also train drivers to conduct routine checks before and after driving the vehicles to ensure that any issues can be addressed promptly. Additionally, I would keep detailed records of each vehicle's maintenance history, to ensure that repairs and preventative maintenance are carried out on schedule.
Sample Numeric Data:
6. A machine produces 10 pieces per minute. How many pieces will it produce in 3 hours?
Candidate Answer: 10 pieces x 60 minutes = 600 pieces in an hour.
600 pieces/hour x 3 hours = 1800 pieces in 3 hours.
7. A hydraulic system has a flow rate of 50 gallons per minute. How many gallons of fluid will the system circulate in 4 hours?
Candidate Answer: 50 gallons x 60 minutes = 3000 gallons in an hour.
3000 gallons/hour x 4 hours = 12000 gallons in 4 hours.
8. A conveyor belt is 20 feet long, and it moves at a rate of 4 feet per second. How long will it take for an item placed at one end of the conveyor belt to reach the other end?
Candidate Answer: 20 feet / 4 feet per second = 5 seconds.
9. A gear system has a gear with a diameter of 10 inches and a gear with a diameter of 20 inches. How many times will the gear with the smaller diameter have to rotate to complete one rotation of the larger gear?
Candidate Answer: The larger gear has twice the diameter of the smaller gear, so it will turn at half the speed. Thus, the smaller gear will have to rotate twice as many times to complete one rotation of the larger gear. Therefore, the answer is 2.
10. A vehicle's gas tank can hold 15 gallons of fuel. If the vehicle travels 30 miles per gallon, how far can the vehicle travel on one full tank of fuel?
Candidate Answer: 15 gallons x 30 miles per gallon = 450 miles.
