I was interviewed on a Monday and was told that they wanted to schedule a second interview. Due to the position starting in less than a month, they wanted a second interview scheduled by the end of the week. I gave my availability for the remainder of the week and was told I would hear back by the end of the current day with the date and time of the second interview. I did not hear back by Wednesday morning, so I sent an email to the individual that interviewed me. On Friday, I left a voicemail after not hearing back. I never did hear back and am disappointed that they could not demonstrate enough common courtesy to tell me that they changed their mind.
