Autodesk Developer interview questions

They flew me over, did several one-on- one interviews, the staff was friendly.HNowever, despite my several follow up messages, after flying me over and spending a whole day, they did not give any response. i found this weird as the interview had gone smooth. It is OK that they may not have thought I was the right person, but no matter what everyone deserves a response. Dead silence is not the curtous way to handle things.
