Tell us about a time when you made a mistake in the lab and how you addressed it.

Sample answer to the question

During my time in the lab, I made a mistake while conducting a gel electrophoresis experiment. I accidentally loaded the samples in the wrong order, which resulted in confusing and inaccurate results. To address the mistake, I immediately notified my supervisor about the error and explained what happened. Together, we reviewed the protocol and identified the step where I went wrong. We decided to repeat the experiment, ensuring that the samples were loaded correctly this time. I took extra care and double-checked the order of the samples before loading them onto the gel. The repeated experiment yielded the expected results, and I learned the importance of attention to detail and following protocols. I now make it a habit to thoroughly review the steps and confirm the correct order of samples before proceeding with any experiment.

A more solid answer

During one of my gel electrophoresis experiments in the lab, I made a mistake by accidentally loading the samples in the wrong order. As a result, the gel produced confusing and inaccurate results. Recognizing the error, I immediately informed my supervisor about the mistake. Together, we reviewed the experiment protocol and identified the step where I went wrong. In order to address the mistake, we decided to repeat the experiment, ensuring that the samples were loaded correctly this time. I took extra caution and double-checked the order of the samples before loading them onto the gel. The repeated experiment yielded the expected results, providing valuable data for our research. This experience taught me the importance of attention to detail and the significance of following protocols accurately. It also highlighted the importance of open communication and collaboration within a team.

Why this is a more solid answer:

The solid answer provides specific details about the gel electrophoresis experiment, the actions taken by the candidate, and the outcome of the repeated experiment. It demonstrates the candidate's attention to detail, ability to follow protocols, and problem-solving skills. However, it could still be improved by providing more examples of how the candidate addressed the mistake and contributed to the team's success.

An exceptional answer

One incident that comes to mind is when I was conducting a gel electrophoresis experiment in the lab as part of a research project. Unfortunately, I made a crucial mistake by accidentally loading the samples in the wrong order. This led to misinterpreted results that had the potential to compromise the accuracy of our findings. Realizing the gravity of the situation, I immediately reported the error to my supervisor, providing a detailed explanation of what went wrong. Together, we analyzed the protocol to identify the specific step where I made the mistake. To rectify the situation, I diligently repeated the experiment, paying extra attention to detail and triple-checking the sample order. This time, the gel electrophoresis yielded the expected results, enabling us to draw accurate conclusions. Reflecting on this mistake, I realized the importance of not only following protocols but also remaining vigilant throughout the entire experimental process. I used this experience as an opportunity to improve my organizational skills and develop a checklist system to minimize the chances of future errors. Additionally, I actively sought feedback from my supervisor and colleagues to learn from their insights and perspectives. By openly discussing the mistake and our subsequent actions, we strengthened our communication and trust within the team, fostering a collaborative and supportive work environment.

Why this is an exceptional answer:

The exceptional answer provides a detailed account of the gel electrophoresis experiment, highlighting the candidate's quick response in reporting the error and seeking guidance. It emphasizes the candidate's proactive approach in rectifying the mistake and the lessons learned from the experience. The answer also demonstrates the candidate's ability to work as part of a team, showing collaboration and open communication in addressing the mistake. Furthermore, it showcases the candidate's self-improvement efforts and their contribution to creating a supportive work environment. The answer not only meets the evaluation areas mentioned in the job description but exceeds them by showcasing strong problem-solving skills, initiative, and continuous learning.
