Distillery interview questions

Unprofessional. Company reached out to me on LinkedIn about the opportunity. After expressing interest, I selected an open time slot on their Google Calendar and communicated such to the recruiter. A few hours later my appointment time changed by 3 hours without any communication or check-in to see if the change in time would work for my schedule. Since it didn’t work, I went into their Google Calendar and scheduled a different day and time that once again was available on their calendar. Fast forward to that day and time, I dial in and no one joins. Five mins into the time I get an email that the meeting is cancelled without any explanation or communication.
