AFRY is a great company with phantastic reputation in the Energy market. I have heard that they do simple cases in their interviews to test your structured thinking, however with a specific industry focus on energy and process industries and a capability focus on operations, process improvement, , e.g. thing like
- What do you think are the main drivers to decarbonize the economy of Spain?
- How do you think about the relative costs of each of these?
- What are the main costs for an oil refinery?
- How could you improve the performance of a specific industrial facility?
Hope this helps.
