Share an example of a time when you had to make a critical decision in the laboratory. How did you approach it?

Sample answer to the question

One time in the laboratory, I had to make a critical decision when an experiment I was conducting started to produce unexpected results. I approached the situation by first carefully analyzing the data I had collected and comparing it to the expected outcomes. I then consulted with my colleagues and supervisor to gather their insights and opinions. By discussing the issue with them, I was able to gain different perspectives and brainstorm potential solutions. After evaluating all the information and considering the potential impact of each decision, I decided to repeat the experiment using a different approach. This decision required me to adjust various parameters and techniques, ensuring that all steps were meticulously executed. The result was a successful experiment with accurate and reliable results.

A more solid answer

A memorable incident in the lab where I had to make a critical decision was during a study on cancer cell growth. As I was analyzing the data, I noticed some inconsistencies that challenged the validity of the results. To address this, I meticulously reviewed my experimental protocols, ensuring that I followed each step accurately. I also cross-checked the calibration of the instruments I used, such as the microscope and cell counter, to rule out any technical issues. Additionally, I consulted with my supervisor and collaborated with other lab members to gain their expert opinions. Together, we identified that the inconsistencies were likely caused by a contamination in the cell culture medium. Armed with this information, I swiftly took action by thoroughly sterilizing the culture medium and repeating the experiment. The second round of experiments confirmed our suspicions and provided accurate results. This experience highlighted the importance of attention to detail, technical proficiency, critical thinking, and collaboration in the laboratory setting.

Why this is a more solid answer:

The solid answer provides a more comprehensive explanation of the critical decision made in the laboratory. It includes specific examples of the candidate's technical skills, attention to detail, and critical thinking abilities. However, it could still be improved by elaborating on how the candidate managed the contamination issue and mentioning any leadership or team management capabilities that were utilized.

An exceptional answer

Let me share with you an exceptional example of a critical decision I made in the laboratory. During a study on the efficacy of a new antibiotic, I encountered an unexpected complication. The results of the antibiotic potency assay were inconsistent, raising concerns about the reliability of the data. To investigate the issue, I meticulously reviewed the entire experimental process, focusing on my technique and adherence to standard operating procedures. Identifying potential human error, I decided to take preventative measures by providing additional training to lab technicians on the proper execution of the assay. Furthermore, I collaborated with a team of experts to perform a thorough review of our lab protocols, placing extra emphasis on quality control measures. Through this collaborative effort, we identified a small temperature variation in the incubator, which was affecting assay results. As a decisive leader, I took immediate action by implementing strict temperature monitoring protocols and recalibrating equipment. The subsequent experiments yielded consistent and accurate results, confirming the efficacy of the antibiotic. This experience not only demonstrated my advanced technical skills and attention to detail but also highlighted my leadership and problem-solving capabilities in navigating complex laboratory challenges.
