Biological Technician Interview Questions
What laboratory equipment are you comfortable operating and maintaining?

Sample answer to the question

I am comfortable operating and maintaining a wide range of laboratory equipment. This includes microscopes, centrifuges, spectrophotometers, PCR machines, electrophoresis systems, and cell culture equipment. In my previous role, I regularly used these instruments to conduct experiments and analyze biological data. I am proficient in handling and calibrating the equipment to ensure accurate results. Additionally, I have experience troubleshooting any minor issues that may arise, such as adjusting settings or replacing worn-out parts. Overall, I have a strong technical background in laboratory procedures and equipment operation.

A more solid answer

I am comfortable operating and maintaining a wide range of laboratory equipment, including microscopes, centrifuges, spectrophotometers, PCR machines, electrophoresis systems, and cell culture equipment. For example, in my previous role, I regularly used a Leica DM750 microscope to examine cellular structures and a Thermo Fisher Scientific centrifuge for sample preparation. I am adept at calibrating and troubleshooting these instruments to ensure accurate results. Additionally, I have a keen eye for detail, carefully following protocol guidelines during experiments and ensuring proper maintenance of the equipment. For instance, I routinely clean and sterilize the PCR machine to prevent cross-contamination. My strong technical abilities and attention to detail allow me to effectively operate and maintain laboratory equipment to support scientific research.

Why this is a more solid answer:

The solid answer expands on the basic answer by providing specific details about the laboratory equipment the candidate is comfortable with, as well as their experience using those instruments. The answer also emphasizes the candidate's attention to detail, technical abilities, and maintenance skills. However, it can still be improved by highlighting the candidate's experience with data analysis software and their knowledge of biosafety and bioethics.

An exceptional answer

I am highly proficient in operating and maintaining a diverse range of laboratory equipment. Throughout my 4 years of experience in a research laboratory, I have regularly used and maintained microscopes (such as Olympus CX43), centrifuges (such as Eppendorf 5427R), spectrophotometers (such as Thermo Fisher Scientific Genesys 10S UV-Vis), PCR machines (such as Bio-Rad C1000 Touch Thermal Cycler), electrophoresis systems (such as Bio-Rad Mini-Sub Cell GT), and cell culture equipment (such as Thermo Fisher Scientific Heracell VIOS CO2 Incubator). I meticulously follow standard operating procedures (SOPs) for each instrument, adhering to strict quality control measures. For instance, I regularly perform calibration checks, validate protocols, and ensure proper maintenance and cleaning to guarantee optimal performance and accurate results. With a strong technical background and attention to detail, I am confident in my ability to operate and maintain laboratory equipment to the highest standards.

Why this is an exceptional answer:

The exceptional answer provides even more specific details about the laboratory equipment the candidate is comfortable operating and maintaining. It also highlights the candidate's extensive experience with each instrument and their commitment to following standard operating procedures and quality control measures. The answer effectively showcases the candidate's technical abilities, attention to detail, and commitment to maintaining equipment performance and accuracy.
