3 Rounds - data engineering(3 coding problems in 45 mins), Statistical theory interview with some machine learning theory question, could not make it to third round. I did not do well in the first round and before my third round they just removed invitation from my calendar without any email or without letting me know that they cancelling the third round. and they emailed me the next day that they have decided not to move forward. Bad experience.

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.
