Notch Video interview questions

A negative and odd experience for an interview. It honestly felt like a diversity interview, just so they said they did. Firstly, they did not inform me that another person was going to join the video call. The start of it all was quite awkward, they told me about themselves and didn't ask me a question to follow, and I went and began to tell them my background. The first person asked me 2 questions and asked the other person if they had any, which they did not. The person who I didn't know was joining barley said anything and just seemed to pear into the camera looking for ques of some sort. Anyway I asked them more questions then they asked me, including some passion projects they had worked on that I showed interest in but they seemed quite uninterested. Again the second person hardly said anything and was just staring the entire time.
