Salesforce Director interview questions

First interview with HR, followed by interviews with several people from various departments (some of them from completely unrelated areas), and the process ended with a live case study simulation. The preparation for the case study was quite intense as the scope of work requested was very wide, which I found kind of unfair as they expect candidates to invest so much time preparing for a final step in the recruitment process. Because there were so many interviewers attending the final case study simulation, I felt that no one took the actual responsibility for guiding me through the recruitment process and properly briefing me for each step, which resulted in misaligned expectations for the final presentation.
