Biological Technician Interview Questions

Sample answer to the question

In my previous role as a Biological Technician, I encountered a challenging situation that required strong analytical and problem-solving skills. We were conducting an experiment to analyze the effects of a certain drug on cell cultures. However, we noticed inconsistent results and couldn't determine the cause. To solve the problem, I thoroughly reviewed the experimental procedure and identified a potential issue with the drug concentration. I decided to perform a series of dilutions to test different concentrations and observe the effects on the cell cultures. Through careful analysis of the data obtained from these experiments, I was able to determine the optimal concentration that produced consistent and meaningful results. This experience taught me the importance of attention to detail and critical thinking in troubleshooting laboratory issues.

A more solid answer

In my previous role as a Biological Technician, I faced a challenging situation where my analytical and problem-solving skills were essential. We were conducting an experiment to analyze the effects of a certain drug on cell cultures using PCR and electrophoresis techniques. However, we encountered inconsistent results and could not determine the cause. To identify the issue, I used data analysis software like Excel and SPSS to analyze the data, looking for patterns or correlations that could explain the inconsistencies. After careful analysis, I realized that variations in the drug concentration could be the cause. I proposed performing a series of dilutions to test different concentrations and observe the effects on the cell cultures. By meticulously documenting the experimental process, including the dilutions and their effects on the cultures, I was able to identify the optimal concentration that produced consistent and meaningful results. This experience highlighted the importance of attention to detail, critical thinking, and effective communication in troubleshooting laboratory issues.

Why this is a more solid answer:

The solid answer addresses the evaluation areas by providing more details about the candidate's experience with data analysis software, such as Excel and SPSS. The answer also mentions the use of PCR and electrophoresis techniques, showcasing the candidate's knowledge of laboratory procedures. However, it still lacks information about the candidate's documentation skills and understanding of biosafety and bioethics.

An exceptional answer

During my time as a Biological Technician, I encountered a complex problem that required advanced analytical and problem-solving skills. We were conducting a study on the impact of a newly developed pesticide on a specific insect population. The goal was to determine its effectiveness and any potential risks. However, we encountered unexpected results in our data analysis, with some insects showing resistance to the pesticide while others were affected. To address this issue, I collaborated with a team of entomologists and researchers to gather additional data and conduct further experiments. We used advanced statistical analysis techniques, such as regression analysis and hypothesis testing, to identify the factors contributing to the resistance. Through this process, we discovered that genetic variations in the insect population were responsible for the different responses. To confirm our findings, we performed genetic sequencing and compared the genetic profiles of the resistant and susceptible insects. This comprehensive analysis allowed us to develop strategies to mitigate the resistance and improve the effectiveness of the pesticide. This experience showcased not only my analytical and problem-solving skills but also my ability to collaborate with interdisciplinary teams and apply advanced laboratory techniques.

Why this is an exceptional answer:

The exceptional answer demonstrates a high level of expertise and experience in utilizing analytical and problem-solving skills in a laboratory setting. The candidate provides specific details about their collaboration with entomologists and researchers, as well as their use of advanced statistical analysis techniques and genetic sequencing. The answer also highlights the candidate's ability to work in interdisciplinary teams and their application of laboratory techniques to address a complex problem. However, it could still be improved by discussing the candidate's communication and documentation skills, as well as their understanding of biosafety and bioethics.
