This helped me keep track of all the data I needed to report back to my supervisor.”

9. Do you have any experience using liquid handling systems?

This question is an opportunity to show your knowledge of the company’s products and services. If you have experience using liquid handling systems, describe how they helped you in your previous role.

Example: “I’ve used PerkinElmer’s OpenLab software for my entire career as a chemist. I find it easy to use and helpful when troubleshooting problems with our equipment. In my last position, we had issues with our centrifuges that were causing inaccurate results. Using OpenLab, I was able to determine which parts needed replacing and order them before any clients noticed.”

10. What tools or processes would you use to debug software?

Debugging is a common task for software developers, and the interviewer may ask you this question to see if you have experience with debugging. Use your answer to highlight your problem-solving skills and ability to debug software effectively.

Example: “I would first use my knowledge of the language I’m working in to identify what type of bug it is. Then, I’d try to replicate the bug by changing one variable at a time until I find the cause. Once I’ve identified the root cause, I’ll fix the issue permanently so that it doesn’t happen again.”

11. Have you ever been responsible for the health and safety of others? Describe.

This question is designed to assess your ability to work in a team and ensure the safety of others. When answering, it can be helpful to mention any specific projects you worked on that helped improve health or safety for people or the environment.
