ExxonMobil Chemical Engineer interview questions

What is the most memorable achievement in your life? Tell me a time where you are facing/ handling a difficult person. Please draw (Zoom whiteboard) me a specific equipment/ process and explain the operating principles behind it. For a given case study (to be presented by the interviewers), please explain the necessary measurements to eradicate this issue.

There will be typical questions for behavioural and technical skills, eg where do you see yourself in the next 5 years? 10 years?
