Ultimately, I want to ensure that our reports are accurate and reliable.”

What is your experience with water treatment?

This question can help the interviewer determine your experience level and how you might fit into their organization. If you have little to no experience, you can highlight other skills that may be transferable from previous roles.

Example: “I’ve worked in water treatment for five years now, but I started out as a lab technician where I tested samples of water quality. After two years, I moved up to working with automated systems where I monitored equipment and made sure it was functioning properly. In my current role, I’m responsible for maintaining all aspects of water treatment, including testing, monitoring and reporting.”

Provide an example of a time when you had to troubleshoot a problem with a piece of equipment.

This question can help the interviewer determine how you apply your problem-solving skills to a variety of situations. Use examples from previous work experiences where you had to troubleshoot equipment and solve problems on your own or with the help of others.

Example: “At my last job, I was working in a lab that used water quality testing equipment to test for bacteria levels in drinking water. One day, we were running a sample when the equipment started beeping loudly. We couldn’t figure out what was wrong with it, so we called our supervisor over to see if she could help us fix it. She looked at it for a few minutes and then told us to run another sample. When we did, the equipment worked fine.”

If a spill occurred in a nearby river, what steps would you take to protect the water source for your community?

This question can help interviewers understand your knowledge of water quality and how you would respond to a crisis. Use examples from previous experience or describe what you would do in this situation if it had never happened before.

Example: “If I were working for the local government, I would immediately call my supervisor and other technicians to assess the spill and determine its source. We would then work together to collect samples of the river’s water at different depths and locations to test for contamination. If we found that the spill was toxic, we would close off the area until we could clean up the mess.”

What would you do if you noticed a coworker was not following safety protocols?

Employers ask this question to make sure you are a team player and that you can help others improve their work habits. In your answer, try to show that you would be willing to speak up for the safety of yourself and your coworkers.

If they were still not following protocols after our conversation, I would report the issue to my supervisor or manager.”

How well do you follow directions?

This question can help an interviewer determine how well you work independently and with others. It can also show them whether or not you are able to follow instructions from supervisors, which is important in this role. When answering this question, it can be helpful to mention a time when you had to complete tasks on your own while still following the directions of a supervisor.

Example: “I am very good at following directions because I like to make sure that I’m doing my job correctly. In my last position, I was working alone but would check in with my supervisor every few hours to let her know what I was working on. She would then give me more specific instructions for what she wanted me to do next.”

Do you have any experience writing technical reports?

This question can help interviewers understand your writing skills and how you organize information. Use examples from previous work to explain what types of reports you’ve written, the different formats you’ve used and any experience you have with technical writing software.

Example: “In my last position as a water quality technician, I was responsible for creating weekly reports that summarized our team’s findings on samples we collected. These reports included details about the location where we took the sample, the date we collected it and the results of our testing. I also wrote monthly summaries that detailed the overall progress of our department’s goals. These reports were more in-depth than the weekly ones and included graphs and charts that helped summarize our data.”

When performing a test, what would you do if you noticed a discrepancy between your results and those of your partner?

This question can help interviewers understand how you work with others and your ability to communicate effectively. When answering, it can be helpful to mention a specific situation in which you noticed a discrepancy between your results and those of another technician and what steps you took to resolve the issue.

In one instance, I was testing for bacteria levels in a local lake when my partner tested for high levels of lead. After checking his test results again, he realized that he had accidentally switched two numbers on his report. We were able to submit the correct information to our supervisor before anyone else swam in the lake.”
