CEO of the company contacted me for an interview, at 10:30. They didn't specify a day. I responded asking them if they meant tomorrow, to which they responded yes. It seemed to push to tell me to meet them tomorrow, rather than ask, but I thought I would show up anyway. An hour our for meeting, the CEO emails to angry about the lack of confirmation for the meeting, and saying they will pass on me as a candidate. His tone was rude and unprofesssional, complaining about "wasted time". Again, he didn't confirmation.
Huge waste of my time. Both poor communication from company, and irrationally emotional responses from the company. I'm glad these problems raised their head before I accepted a position with the company.
