Crayon Key Account Manager interview questions

I sent a resume from a job board. 1 Month later, I received a calendar invite...no call... just an invite for a phone interview. The person did not call. No note..no contact from them. I requested a reschedule via email. Did not hear anything for a week. Tried again and they replied. They are in the final stages of hiring someone else and will keep my application on final. Perhaps the most rudest company I have ever dealt with.
