Tell me about your ability to work under pressure?

Answer tips

You may say that you thrive under certain types of pressure. Give an example that relates to the type of position applied for.

Mention routine pressure you face, such as dealing with deadlines on a regular basis.

Try not to use an example where you created the pressure yourself, by waiting too long to start something, or by handling a task irresponsibly at the beginning. For example, working under pressure to meet a customer’s deadline could be a good example, but not if you had waited too long to start the project.

“Pressure is actually a catalyst to my work. When there is an imperative deadline, I refocus my energy into my work which in fact, has helped me to produce some of my best works. (Give examples) I guess you can say I thrive under pressure.”

What to look for in an answer:

  • Commitment to following safety protocol

Mechanical Technician Interview Questions and Answers

Are you familiar with the safety protocols for working with hazardous materials?

The interviewer may ask this question to assess your knowledge of safety protocols and how you apply them in the workplace. Use your answer to highlight your understanding of OSHA regulations, as well as any other safety standards that apply to your industry.

Example: “Yes, I am familiar with the safety protocols for working with hazardous materials. In my last role, I worked on a team that handled dangerous chemicals, so we had to be especially careful about following all applicable safety procedures. We always wore protective gear when handling these substances, and we also implemented secondary containment methods to prevent spills from spreading. These precautions helped us avoid accidents while still completing our work.”

What are the steps you would take to troubleshoot a malfunctioning pump?

Mechanical technicians often need to troubleshoot problems with machinery. Interviewers ask this question to see if you have the necessary skills and experience to complete these tasks. In your answer, explain how you would approach a problem like this one. You can also mention that you will refer to technical manuals or other resources for help.

Example: “I would first check the pump’s power supply. If it is working properly, I would then move on to checking the wiring. After that, I would inspect the motor and make sure there are no loose connections. Finally, I would look at the pressure switch to ensure it is functioning correctly.”

How would you go about troubleshooting a malfunctioning furnace during the winter season?

This question can help the interviewer assess your troubleshooting skills and ability to work under pressure. Use examples from previous experience to highlight your problem-solving abilities, attention to detail and critical thinking skills.

Example: “I would first check for any obvious issues such as a broken wire or loose connection. If I find no problems with these components, I will then proceed to check the thermostat settings and ensure that it’s set at the right temperature. Next, I’ll check if there are any power outages in the area and whether they’re affecting the furnace. Finally, I’ll check the gas supply and make sure it’s turned on.”

What is your process for documenting your work and recording any changes you made to a machine or system?

Interviewers may ask this question to understand how you keep track of your work and the changes you make. They want to know that you can document your work in a way that is easy for others to read and understand. In your answer, describe your process for documenting your work and include an example of how you would do so if you were working on a project with them.

Example: “I use my computer to record all of my notes about each machine I’m working on. I take pictures of important parts of the system or machines I’m working on and write down any notes I have about those systems. Then, I create a detailed list of what I need to do to complete the job. When I finish one task, I update my notes with the new information.”

Provide an example of a time when you had to use your creativity to find a solution to a problem.

Mechanical technicians often have to use their creativity and problem-solving skills to find solutions to problems. Employers ask this question to see if you are able to think outside the box when needed. In your answer, explain a time when you used your creativity to solve a problem. Explain how your solution worked and what the results were.

Example: “At my last job, I was working on a project that required me to build a custom part for a client’s machine. The part had to be built out of metal, but the original design only called for plastic. To create the new part, I had to figure out a way to combine two different metals together. I decided to try using an alloy to connect the two metals. It took some trial and error, but eventually, I figured out the right combination of metals to make the part.”

If you could only use three tools to complete a job, what would they be?

This question is a way for the interviewer to assess your mechanical knowledge and determine if you are familiar with their company’s tools. It also helps them understand what kind of person you are, as they can see which tools you value most. When answering this question, try to include some of the tools that the company uses in its work.

Example: “If I could only use three tools on any job, it would be my torque wrench, calipers and micrometer. The torque wrench is essential because it allows me to tighten bolts at the right pressure, which ensures the safety of the equipment. Calipers allow me to measure parts accurately, while the micrometer allows me to make sure those measurements are accurate.”

What would you do if you were assigned to work on a project you were unfamiliar with?

This question can help the interviewer determine how you approach new projects and whether you are willing to learn. Your answer should show that you enjoy learning new things, but also highlight your ability to apply your skills to unfamiliar situations.

Example: “When I am assigned a project I’m not familiar with, I first ask my supervisor for more information about it. Then, I research the topic online or in books until I feel confident enough to begin working on it. If I still have questions while working on the project, I will ask my colleagues who have experience with similar projects.”

How well do you work under pressure?

Mechanical technicians often work in high-pressure situations, such as when a client needs an urgent repair. Employers ask this question to make sure you can handle pressure well and complete your tasks on time. In your answer, explain that you are able to manage stress well and have experience working under pressure. Share a specific example of a time you worked under pressure and how you handled it.

Example: “I am someone who handles pressure very well. I’ve been working with deadlines for years now, so I know how to prioritize my tasks and get them done quickly. For instance, once at my previous job, we had a rush order come in. We needed to finish the project by the end of the day or else our client would be charged extra. I was able to stay focused and got all of my work done before the deadline.”
