Autodesk Software Developer interview questions

I had 2-3 interviews. In the last one they said that they didn't know why they are interviewing me because I didn't have enough experience in a certain skill and that they needed to think about it, and still this interview was almost an hour. After all the hours I spent for the process they sent that general email saying they continue with other candidates, they didn't even call. I asked them why they interviewed me and they ignored me.

1) The interviewer quickly went over one of my projects on Resume. 2) Some very simple SQL questions regarding database design. 3) An algorithm question with couple of follow ups that are medium level.
