I met with the *Chief talent officer (had to look up this title from my original schedule with them...) for one of my interviews and she spent half the time telling me why the stock price was so low "We were high on a $300 share price and thought we were gods." Then, the other half telling me her favorite firing stories. I don't know what the purpose of all of this was but it gave me the impression that HR/head of HR needed to demonstrate how important they are in the company.
One of my potential colleagues interviewed me and gave me a fizzbuzz question. I successfully answered it. He then asked me to rewrite it with some restrictions. I did this. Then he asked me to do it one more time. I wasn't familiar with the python syntax for if-else shortcut (e.g., x = 100 if y is True else 0) and so couldn't rewrite it to his liking. This lack of familiarity with this python trick resulted in feedback at the end of the interview that I did not have a deep enough understanding of computer science.
I honestly could tell that the interviewer giving me the fizzbuzz questions wasn't clicking with me personally. That's fine, and I completely respect that it's a valid reason not to hire someone. However, because of this feedback, and the fact that the people at netflix generally liked me, they wanted me to work on some sort of data warehouse management team. I'm not sure why they would offer me a job so wildly different from what I was contacted to apply for, or why the syntax from one language would be considered representative of my knowledge of CS.
Overall, I think the experience of one person at a company is nothing more than an anecdote that can be entertaining, perhaps moderately informative, but it's not a complete picture. There are many stories out there about people interviewing with or working for Netflix. If you are seriously interested in the company, read a lot of those stories, discount all of them as biased, and then see for yourself by talking to them.
