Had phone interview and the supervisor said it went well that they would like to set up a second interview for later that same week. When it came time to interview, they never called. I reached out to them and was unable to reach them so I left a message. I received an email the next day stating that they had gone in a different direction. I am fine if they didn't want to move forward with my application, but don't set up a second interview and then not show up; it's extremely unprofessional.
