Rather long, in a way that they tried to appear organized but it was as if they had no intention to hire anyone. The position had been open for 7-8 months prior to me getting a call, and then the final interview seemed like they wanted to get information about my previous organisation. How they functioned, road blocks etc. Only 1-3 basic skill question for me but that is it. The HR insisted there would be case study etc but none of that was asked. I spent a lot of time preparing. For a process which took months (from the initial HR phone call, to test, to HR prep, then the interview) I wish they could just make up their mind. Did not appreciate them wasting my time, showing no clarity and not giving the right information or responding on time.
