Shell Interview Questions, Process, and Tips

This round was online through HireVue. The interview questions are the basic personality questions such as tell me about a time:
-When you showed leadership
-Managed working in a challenging situation
-Demonstrated resilience

The case study encompassed a lot of factors that analyst must consider when making business decisions. Facts must be used to support arguments towards making a specific decision. The company gave me the case material a week prior to the case study interview.
