Zillow Senior Project Manager interview questions

Initial phone screen with a recruiter (recruiter #1) Phone interview with the hiring manager (set up by recruiter #2) In person interview onsite with 4/5 different folks individually. (set up by recruiter #3) Beautiful offices downtown Seattle. I had to wait longer than expected as the recruiter was late to bring me to the interview huddle room. I had 4/5 separate interviews with various people on working teams. They all were very nice and asked expected interview questions. Upon completion, I was told I'd hear back either way within a week. I've replied numerous times to the recruiter emails with radio silence. Its now been over a month and assuming I did not get an offer, but the fact is that I was told I'd hear back and instead heard nothing is a bit disheartening. Zillow still seems like a good place to work and continues to be on my short list of desired employers but the lack of communication was unprofessional. I didn't like how I had to work with so many different recruiters. They never replied to any of my emails and instead started new threads. I never knew anyone's email address as everyone I dealt with was hidden behind the generic "@jobvite" email address.
