Fannie Mae Senior Applications Support Engineer interview questions

Got a call from FannieMae and a phone screening was set up , phone screening happened within 3 days , questions were mostly basic technical , got good feedback and was called in for an in person interview. In person interview was taken by three persons and was asked lot of questions technical and behavioral as well. Somehow i didn't liked the attitude they had and was not getting a good vibe ,although i was able to answer most of their questions. Total process was about 2 weeks , after 2 weeks i get an email from HR saying the position that i had applied for was cancelled .
