Netflix Senior Software Development Engineer interview questions

I was contacted via LinkedIn by someone from Netflix about a position that my work history suited. I had 3 phone calls / interviews with people from Netflix. 1. Casual conversation with recruiter about why I was interested in Netflix and what I thought about the field in general. 2. Technical phone screen with an engineer on the team which lasted an hour . Some of the questions : 1. What is the difference between encryption and hashing ? 2. Questions about Http Status codes and what they meant . 3. Question about how one would implement a caching server. 3. After the technical screen, I had another technical screen with the director of the team that I was interviewing for . I was asked design questions and about why I was planning to leave my current position. After the phone screens I was extended an offer to fly down to Los Gatos for a full day of interviews. The entire day of interviews was scheduled in 45 minutes intervals and looked like this . 1. HR Rep for the org that was hiring , general questions about how my flight was and wishing me luck with the rest of the day . This took 45 minutes. 2. Senior Engineer from the team, technical interview where engineer and I debugged a hypothetical failure scenario with their online service. This took 45 minutes. 3. Engineering manager for the org, behavioral interview about how I managed dependencies between two different teams and what kind of culture I'd need for this to succeed. 4. Engineering lead who I'd be reporting to, if I was hired. Technical interview which was pretty easy and some behavioral questions about how I'd react in certain team settings. 5. Senior Engineer from the team, another technical interview, we discussed a program to solve Crossword puzzles in a news paper using a program. How is Ping implemented ? ( this is such a random question, I had already read about this question from GlassDoor and knew the answer, but still ). 6. H.R.Director for the org containing the team I was interviewing for. Discussed if I was willing to move to San francisco if they offered me a job and what I was passionate about and what motivates me. Behavioral interview. 7. Vice President of the org that I was interviewing for, general questions about motivation. I expressed concerns that their policy of fire the non-performers scared me because performance is very subjective. and from what I could gather, they didn't have a common set of criteria they followed for judging performance. I was asked if I would reject an offer if they made me one that day, we discussed why I had to think about it. 8. Engineering Director that I had the phone screen with before I flew down. I was pretty much tired and done by the time this interview rolled around, I told the guy that I was quite tired and apologized in advance if I yawned while this was going on. We talked about some self-projects of mine that he had looked at and was impressed by. After the interview, he led me to the reception and I flew home. Two days later I got a call from the H.R. rep congratulating me and asking me to fly down again. Sensing another day long theatrics of interviews, I politely declined and hung up.
