Can you describe a lab experiment you conducted that did not go as planned? What did you learn from it?
This question assesses your problem-solving skills and ability to learn from failures, which are crucial for a junior chemist in an industrial setting.
How to answer
- Provide a clear overview of the experiment and its objectives
- Explain the specific issues that arose during the experiment
- Discuss the steps you took to troubleshoot and resolve the problems
- Highlight any insights gained and how they will inform your future work
- Mention any changes you would make to improve the process in the future
What not to say
- Dismissing the failure as unimportant or blaming others
- Failing to mention any specific learning outcomes
- Being vague about the experiment details
- Not addressing how the experience will impact your future work
Sample answer
“During my internship at BASF, I was tasked with synthesizing a new polymer. The reaction did not yield the expected results due to an unexpected impurity. I analyzed the process and realized I had not accounted for contamination in the reagents. This taught me the importance of reagent quality checks before any experiment. In the future, I will ensure thorough preparation and quality control to avoid similar issues.”
