Received email to choose times for an initial interview. Received a second email on the day of the interview to do it again; turns out they wanted to reschedule (without sending any kind of correspondence besides the system generated email.) Chose new day and time. I entered the Zoom interview a few minutes early and waited for about 20 minutes; no one showed up. Emailed the talent acquisition person about 5 minutes into the zoom interview asking if were still on... no response. Never heard a thing from them again.
