Questis interview questions

Met with CEO twice. We had two amazing conversations about the role and Questis. I don't think I've ever felt so excited to join a company. CEO I would be hearing from them to schedule last two culture fit interviews. That never happened! Got completely ghosted. I sent follow ups and thank you's. I was left in the dark. I come to find out on Linkedin they hired someone else. Such a rude experience in the end.
