Lengthy and thorough interview process. I had a total of 5 video calls with various team members over the span of about 4 weeks. All people I spoke to were very friendly and kind. It was an enjoyable process overall. I was not given any specific reason or feedback as to why I wasn't offered the job opening. I emailed asking for specific feedback, and was told it was a decision based on the needs of the team, not on anything reflective of my performance. I would interview with McChrystal Group again if the opportunity arose.
