Beyond, Inc. interview questions

Applied online and got a request for Hirevue (online interview). Initial screening from a manager of the team and then was called in for an hour and a half interview with team mates, Manager and the director. Everything seemed positive and after a couple of hours I sent a thank you email to the HR and her response was positive too. I hadn't received any feedback on the day the HR promised to get back . I emailed her the next day and she wanted me to take the hirevue again for another team and I was extremely confused. I replied back asking her for the feedback of the interview and she did not reply back the next couple of days. I then received another offer from some other company and left her a voicemail saying that I am still waiting on the interview feedback to make a final decision. Again no reply for a couple of days, again emailed her about the offer and she finally replied back saying that I need to come in for another interview. I accepted that too thinking that it was the next step. Then she made clear that this was not the next step but a completely new interview for another team. And she added that the team I interviewed for had recruited some one else. Do they not think that I needed a formal reply that I did not get through the interview. So much of confusion, absolutely zero professionalism. I would never interview again with overstock.
