Same experience as everyone else. They sent me a case study and asked me to complete it as soon as possible. It took me about two hours but I did complete it. After a week I received a rejection email without any explanation.I noticed they posted the same job a few times. . At this point I am starting to wonder if the case studies are real problems they are currently having and they are just getting free ideas on how to problem solve. I wish I had read the reviews before wasting my time.
