Applied Value Technologies interview questions

Multiple interviews via MS Teams with various levels of management and you have to sign an NDA. After the second or third interview it really feels like you're in, but then the send you a very generic rejection email with zero personal feedback. I would think after 3 interviews their be something you could say to help the candidate improve.

People where friendly and truthful about the obstacles that needed to be overcome by the role. There was 4 interviews but we probably could have had it done in 2.
