Send you an email with a set of case study questions about pricing, and need you to finish a strategy answer. The questions are very close to their business. They said they would have an interview to discuss the answer. However, when you send back your answers, they will say you are not fit. It seems to help them to think about the future pricing strategic plan without any pay. There are no questions about any quantitative topics. Very bad interview process. If you want to consume your time, try to apply for it.
