Meta Partner Engineer interview questions

I applied online and got into a phone screening with one of the recruiter. Basically he asked me about my background and described the role. I thought went pretty well, but I got no follow up.

Spoke with a recruiter for a half an hour about the role and my interest. The recruiter asked me to send in availability to start the interview process. I emailed them back promptly after the call but haven't heard from them since. I sent several follow-up emails and still haven't heard anything. It was a frustrating experience because I was ignored almost immediately after being told I was going to be scheduled for an interview. All in all, it was a sad and disappointing experience.
