About the role
This interview covers the practical fundamentals a graduate process engineer uses around vessels, exchangers, pumps and control loops. The panel wants to see disciplined calculations, structured troubleshooting, respect for process safety and clear communication with plant operators.
How to prepare
- Revise mass and energy balances, phase separation, pressure drop, heat transfer and basic process control.
- Practise reading a simple process flow diagram and tracing what happens when one variable changes.
- Review how alarms, trends and field checks are used to investigate a plant deviation.
- Prepare an example that shows how you verified a calculation rather than accepting the first result.
- Rehearse explaining process risk without relying on unexplained technical terms.
Common mistakes
- Giving a calculation without stating the basis, units or assumptions.
- Changing a set point before checking instruments, process conditions and authorisation.
- Discussing production targets while ignoring loss of containment or overpressure risk.
