Pure scam based on marketing value
So far, this is a scam. I took the exam WITHOUT preparation and got 55%. After intensive preparation, I took it again. With 15 minutes left, I had re-checked 15 out of 17 questions. One was unresolved and one was partially complete. The tasks were pretty easy, yet I only got 62% (66% needed).
They offered me a free retake or a $75 manual rescore, stating: "Please complete payment ASAP for the rescoring fee at [link]." I paid it, but there has been no reaction at all for six days. When I checked the support ticket, it became obvious that their system is not syncing with their emails, so I have to duplicate my messages. This is the worst experience for someone like me who holds several Oracle and Confluent certifications. I will update this post, as I’m 100% sure the story doesn't end here.
