Can you describe a laboratory procedure you have followed in your previous experience and how you ensured accuracy and safety?
This question assesses your understanding of laboratory protocols, attention to detail, and commitment to safety, which are crucial for a Junior Bench Chemist role.
How to answer
- Start by outlining the specific laboratory procedure you followed
- Detail the steps you took to ensure accuracy, including any calibration or validation methods used
- Discuss the safety protocols you adhered to, mentioning specific equipment or personal protective gear
- Explain any challenges you faced during the procedure and how you overcame them
- Conclude with the outcome of the procedure and what you learned from the experience
What not to say
- Giving vague descriptions without specific details about the procedure
- Neglecting to mention safety protocols or personal protective equipment
- Focusing solely on the results without discussing the process
- Failing to acknowledge the importance of teamwork or collaboration in the lab
Sample answer
“In my previous role at a local pharmaceutical lab, I was responsible for performing titrations to determine the concentration of active ingredients in our formulations. I meticulously calibrated the equipment before use, ensuring accuracy to within 0.01%. I always wore the appropriate PPE, including gloves and goggles, and followed our SOPs to mitigate risks. During one experiment, I noticed an anomaly in the readings, which led me to double-check the reagents and recalibrate the equipment. This attention to detail helped prevent a potentially costly error, and I learned the importance of vigilance in laboratory work.”
