10 minutes before the scheduled HR call, I received an email from the HR saying she needed to pick up her child, hence canceling the interview. (This is a remote position, so their employees can quit during the middle of the day for personal errands?) She also asked me if the following day at a specific time would work. I had a meeting at the exact same time. I replied saying except that time, I can do any other time the following day or the day after. I never heard back. One week later, I sent her an email follow up. No response. I don't know what happened, but this is so unprofessional.
