Choose the right perspective
Match the person's side of the industry, such as a mine operator or a mining equipment maker, and their engineering focus to the decision you face. Check whether their relevant role is current or past, and ask for one engineering decision they owned and how it played out on site.
Questions to take into the conversation
- 01Tell me about a time when equipment or process constraints forced you to choose between lower upfront cost and higher operating cost. What did you choose and why?
- 02Which technical factors have surprised you most when they affected how reliably a system actually performed in the field?
- 03Describe a decision you made about equipment or operations that you would handle differently now. What did you learn?
