How to answer
What not to say
Example answer
“At BASF, I encountered a severe corrosion issue in a pipeline transporting aggressive chemicals. Using failure analysis techniques, I identified localized corrosion due to microbially induced corrosion (MIC). I collaborated with microbiologists to develop a biocide treatment plan, which, after implementation, reduced corrosion rates by 70% and extended the pipeline's lifespan significantly. This experience taught me the importance of interdisciplinary collaboration in solving complex engineering problems.”
