There were 3 rounds of interviews, the inital screening, interview with a Director and then with two project managers. They did require 2 assignments for the last two interviews and those did take additional prep time. They were responsive, helpful for questions and professional.

6 rounds of Interviews with all the executives around the globe including a written test which took about a month for a 'contract' position. They said it went very well and wanted to conduct reference check. Before the ref checks, apparently a local employee gathered malicious unsolicited feedback from an undisclosed past colleague and they took it more seriously than my stellar formal references. In the end, I was not offered the job. What an irony for the world's largest leadership institute to behave so un-leader like.
