Candidate interview experiences
First-hand accounts from people who interviewed at Petrofac.
Process Engineer
I first had to complete a questionnaire, and then I was invited to an interview on Microsoft Teams. There, three interviewers asked me questions about the company, which required me to do some research and connect it with my university studies related to the role.
- What's your understanding of our company and our supply chain?
- What are your thoughts on this role and your potential contributions?
Process Engineer
The interview was pretty challenging, mostly featuring scenario-based questions. Towards the end, there were also some technical questions. The main focus was on Heat Transfer Operations, and the entire interview lasted about an hour.
- Could you explain the heat transfer principles that apply to cooking?
Process Engineer
Interviewed by the lead/senior engineer. It was very technical. Started with a paper test on engineering concepts. The interviewer then discussed my answers and I had to explain/justify them. I tried to explain in a way that showed I understood the concepts. It was okay if I didn't know, just be honest and show willingness to learn. They wanted to see my ability to explain and communicate clearly. Then some questions about my CV (past projects/experience). Very little (if any) behavioral questions.
- Tell me about yourself.
- Explain fluid mechanics, thermodynamics, and heat transfer concepts.
- What is the difference between boiling and dew points?
