Wow, I had nearly the exact same interview process. Super aggressive to nearly combative recruiter (felt like I was being argued with the whole time), fizzbuzz question, left in a conference room alone for an hour for lunch, a few more questions then done.
I got an offer but turned them down because their recruiter was so crazy aggressive it made me feel that Netflix would be a very unhappy place to work.
From what I've heard from ex-employees (one a recruiter) the hiring/salary/firing process there is not well organized. People often make more than managers or more senior employees and large layoffs every year for the 'bottom 10%' make for some weird social dynamics.
As much as I respect and admire their technical processes there I'm not convinced it's really a good place to work.
