21. Presenting technical research or results to someone without a scientific background can be tricky – how do you handle this situation?

Why this is important: The ability to communicate scientific information and results, even to those without a scientific background, is essential for any laboratory professional. Asking this question allows hiring managers to assess prospective employees’ communication skills and ability to explain complex concepts in simple terms effectively.

Model answer: Whenever I need to present technical research or results to someone without a scientific background, I start by understanding their level of knowledge in the subject area. This helps me frame my explanation around concepts they can likely comprehend rather than diving into complicated jargon that may confuse them. Additionally, I provide visuals where necessary to help explain any complex data points or findings more clearly. Finally, I always strive to speak in plain language that anyone can understand rather than relying on technical terms. I can effectively communicate technical research or results to any audience by taking a thoughtful approach and speaking clearly.

22. Describe a situation when you identified an issue while testing a sample. How did you address it?

This is important: Laboratory professionals must identify sample issues or irregularities before beginning tests or experiments. Asking this question allows hiring managers to evaluate the prospective employee’s attention to detail and ability to think critically when identifying potential problems.

Model answer: While experimenting on a soil sample, I noticed some strange particles mixed in with the soil. To address this issue, I took a closer look at the selection and identified that these particles were bits of plastic, which could contaminate the results of my experiment. As soon as I recognized this issue, I quickly adjusted my testing procedure to account for this contamination. To ensure accurate and reliable results, I set up a more comprehensive filtration system to remove any foreign particles from the sample before beginning the test. By taking swift action and making sure to consider all possible variables, I was able to complete my experiment without compromising its integrity.

23. Are you confident requesting assistance when unable to identify irregularities in a sample? Can you illustrate how this works for you?

Why this is important: Laboratory professionals need to recognize when they may not have the expertise necessary to correctly identify an issue with a sample and seek help when needed. Asking this question allows hiring managers to assess prospective employees’ ability to work collaboratively and their willingness to reach out for help when faced with something unfamiliar.

Model answer: Yes, I am confident in requesting assistance if I cannot identify irregularities in a sample. For example, while testing a water sample for contamination levels recently, I noticed some unexpected results that didn’t add up. After researching independently and consulting with colleagues with more experience in this area, I could still not determine the cause. In this case, I decided to reach out to a more senior technician in our lab who had experience analyzing water samples. By asking for their help and expertise, I better understood the situation and ultimately troubleshot the irregularity I had initially noticed.

I believe it’s essential to recognize an issue outside my knowledge base and seek assistance from those with more expertise to ensure accurate results. Working together and collaborating is always beneficial, especially within the laboratory setting. Thus, I have no problem reaching out for help if needed.
