Control Risks interview questions

Three rounds of interviews and a writing test. The process was fairly quick with immediate feedback after each round. However, after the final interview, there was dead silence and when I reached out and they asked a few questions including notice period. No offer. When scheduling interviews, they didn't ask for my availability and instead just notified the schedule

Multiple interviews with other partners, very easy and collegiate. I knew a few partners at the company so it was an easy process. We discussed the makeup of the team, structure of the company and what would be expected and in what time frame (in terms of revenue).
