Cohen & Steers Associate Director, Project Management interview questions

This company made me a tentative offer and rescinded it at the last minute for someone else after I had come to their office for an in person interview. The first round was a standard conversation with a leader of their team, and was standard. There were no cross-examination questions, and they quickly put me through to the second round of the interview process. The second round was a six hour written exam. The company sent this exam and all related materials to me late. After I handed this in, I was asked to attend more interviews, and a comprehensive background check process, provide references, etc. Once this was complete, they rescheduled my final interview with the team, that was set to be in person, minutes before I arrived at their New York City office for the first meeting. While I was enthusiastic at the prospect of working there, they were largely inconsiderate of my time throughout a majority of this process.
