Biological Technician Interview Questions
How do you conduct experiments and investigations under supervision?

Sample answer to the question

When conducting experiments and investigations under supervision, I follow a systematic approach to ensure accuracy and reliability of the results. I carefully review the experimental protocol and coordinate with my supervisor to clarify any doubts. I prepare the necessary equipment, reagents, and samples, ensuring they are properly labeled and organized. During the experiment, I meticulously follow the established procedures, making note of any deviations or unexpected observations. I collect and record data accurately, using appropriate software for analysis. After completing the experiment, I clean and maintain the equipment and dispose of any hazardous materials following safety guidelines. Throughout the process, I maintain open communication with my supervisor, asking for guidance or feedback when necessary.

A more solid answer

When conducting experiments and investigations under supervision, I adhere closely to the provided instructions and protocols to ensure accuracy and reliability of the results. For example, in my previous role, I assisted in a study investigating the effects of different fertilizers on plant growth. I followed the experimental protocol meticulously, measuring the appropriate amounts of fertilizer, ensuring consistent environmental conditions, and collecting data at specified time points. I maintained detailed records of my actions and observations throughout the experiment, making note of any deviations or unexpected results. I also effectively communicated any concerns or questions to my supervisor, seeking clarification when needed. Additionally, I have experience using data analysis software like Excel and SPSS to analyze and interpret the collected data, presenting the findings in clear and organized reports.

Why this is a more solid answer:

The solid answer provides more specific details about the candidate's experience and showcases their ability to follow instructions, pay attention to detail, and effectively communicate and document their work. However, it can be further improved by highlighting more technical abilities and addressing compliance with safety regulations.

An exceptional answer

When conducting experiments and investigations under supervision, I approach the process with a meticulous and organized mindset. I start by thoroughly reviewing the experimental protocol and consulting with my supervisor to clarify any doubts or uncertainties. To ensure accuracy, I double-check the measurements of reagents, prepare samples with precision, and verify the functionality of laboratory equipment before starting the experiment. Throughout the procedure, I meticulously follow the established protocols, recording detailed observations and data at each step. In one project, I collaborated with a team to investigate the impact of different antibiotics on bacterial growth. I not only performed the experiments, but also took the initiative to optimize the protocols and troubleshoot any technical issues that arose. I demonstrated my technical abilities by confidently operating advanced equipment, such as microscopes and spectrophotometers, and conducting techniques like polymerase chain reaction (PCR) and electrophoresis. To ensure compliance with safety regulations, I strictly followed biosafety procedures, properly disposed of hazardous waste, and ensured the maintenance and calibration of safety equipment. Given my strong organizational and documentation skills, I efficiently managed multiple experiments simultaneously, maintaining clear and comprehensive records of laboratory activities. Overall, my approach combines attention to detail, technical expertise, and compliance with safety standards to conduct successful experiments under supervision.

Why this is an exceptional answer:

The exceptional answer goes above and beyond by providing specific examples, demonstrating a higher level of technical abilities, and emphasizing compliance with safety regulations. It showcases the candidate's ability to optimize protocols, troubleshoot technical issues, and effectively manage multiple experiments simultaneously.
