Automattic Machine Learning Engineer interview questions

I was reached out by a recruiter who told me about the position and the tech stack, which I had some questions/concerns about that she wasn't able to answer accurately, instead I was sent a list of articles which (as interesting as they are) didn't answer my questions. I asked to have a quick chat with the team lead before proceeding. At this point, I think the recruiter mistook me for one of her tinder matches or something since she stopped responding to my emails with zero explanation on what's going on.
