Hi Tom,
Firstly, welcome to our forum! You’ve got some good ones there, but here are some more that you should consider:
What do you know about [insert TOC] company?
Can you tell us a time when you’ve worked under pressure?
Describe a time when you’ve had to communicate important information to a group of people?
Have you ever had to respond to an emergency situation? Describe how you reacted.
These are just a few, but hopefully, they’ll help. I recommend thinking of times you’ve demonstrated working under pressure, good customer service, unsupervised and safety focussed.
Do you have a specific TOC you’re applying to?
