I found the following ten interview questions useful when recruiting Project Managers and Project Engineers.
Engineering, Procurement & Construction Skills
- What design disciplines are you comfortable working with?
- What engineering standards have you been involved with?
- What has been your purchasing authority?
- What are the main weaknesses of construction contractors and what have you done to improve their performance?
- How do you motivate people to work safely?
Project Management Skills
- What action have you recently taken when the plan is not being met?
- What is your biggest project achievement so far?
- Which parts of the job do you particularly like doing?
- Describe an important lesson that you learned from your last project?
- What have you done to keep up to date with project best practices?
Note I never needed all of these interview questions to establish a view of the candidates so please treat as a shopping list and pad out with questions specific to the role in question.
