It was a fresh way to tackle the problem that blended technology with traditional geochemistry.

Employers ask this question to see how methodically and effectively you handle technical problems that can impact lab results. You need to explain that you identify the root cause by reviewing error messages and data, then systematically test and calibrate the equipment, and communicate clearly with your team or support staff to resolve the issue.

Example: When I encounter issues with lab equipment or software, I start by carefully observing the problem and reviewing any relevant data to understand what's going wrong. I then work through a logical troubleshooting process, testing each potential cause until I pinpoint the issue. If needed, I discuss the problem with colleagues or reach out to technical support to find the best solution. For example, I once resolved a calibration error by checking both the instrument settings and software updates step by step.
