PLOS interview questions

I was contacted a month after I applied for an initial Zoom video call with someone from their hiring team. During this video call, I was given an overview of the company, role, and interview process, and was told that they don't let more than a week go by during each stage of the interview process. They were also upfront about what the salary would be, and that I would be hearing back from them within a week for next steps. Almost two weeks later I was contacted for the next stage, which was another Zoom video call with two people from the team. The questions they asked were very much personality-based, and not based on any of my experience. At the end of this conversation, I was told they would be getting back to me in two weeks because they had so many other people to interview. Two weeks came and went, and then I got an automated email notifying me of rejection. As another person here noted, if they were just going to reject me via automatic email I'm not sure why it had to take almost three weeks. Overall, communication was lacking and they did not live up to the expectations that they had initially set.
