4 stages, first with CEO, second with Head of Research, Case Study and final in-person interview? Case study was to be completed on Notion and they said would take 3h but was closer to 30

Had an initial video call with one of the team. Was told I would hear back from them in a couple of days, never heard back from them. The interviewer didn't have much structure, and when asked questions at the end about the company, the interviewer did not know any of the answers.
