Zillow Senior Software Engineer II interview questions

The interview process was quite bad. Wasted my time completely. Have tried for nearly two weeks to schedule an interview, then, after finally scheduling the final interviews, I get an email two days before that the position is no longer available. I was genuinely looking for something with them, and delayed some other offers to do these interviews. My fault. Very off-putting system. But I get it, stuff happens. What I am largely frustrated by was the recruiter's inability to respond to me. It was like he had some bitter vitriol towards responses. Mind you, over the past month or so, I have sent him several emails/texts to try and get something going. Not *ONE* response. Not a measly, lone, singular response.
