Morgan Stanley Project Manager interview questions

A phone call from hiring manager for initial screening, and then asked if I can be in a video interview in a couple of hours, and proceed to setup a video interview. There was a case study where I was given 30 minutes to prepare for. The key issue I have is I have asked a very important question that determines the preparation of the case presentation. The hiring manager gave me incorrect information that led me down the incorrect path. In the presentation, he tries to justify that I didn't ask the right question in front of his manager, and I was "thrown under the bus" in the interview. Follow up phone calls and email weren't returned. They are not ethical and interview setup was poor.
