Difficult Interview

Application

I applied through a staffing agency. I interviewed at Netflix in August-2017.

Interview

The onsite interview was 5.5 hours long. I met with 7 people. There was lots of product oriented questions. It was an exhausting day. You can expect coding questions, product-sense questions, A/B testing, experimental design and metric design. Read the culture deck! Read the culture deck! Read the culture deck!

    Average Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Netflix in March-2017.

    Interview

    Manager direct contact. Scheduling failed to contact me. Followed up with initial contact. Scheduling set appointment, then rescheduled. Technical meeting was prototypical example of bad interviewing - looking for specific answers to domain specific questions without giving sufficent context. Looking for answers that match existing biases in the org. I didn't fit the mold, so although I was told I'd be contacted for more details, that never happened - and I don't mind.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 2 weeks. I interviewed at Netflix (Campbell, CA (US)) in August-2012.

    Interview

    Contacted by HR recruiter through LinkedIn, they came back only after a month for phone screening. This was followed by phone screening by hiring mgr, it was very quick <15 mins, I was told that I will get in-person interview soon.

    In-person scheduling happened very quickly too. I interviewed 4 ppl, 45 mins each. HR person was very nice, approachable and easy to converse with. The following 2 ppl from peer teams also were quite nice; I was asked SQL questions and analysis approach which I expected to be asked.

    The last 45 mins was with hiring mgr who seemed a bit uptight. He/she asked a very in-depth SQL question to solve a problem he/she had recently worked on. It was interesting to me that he/she would ask something which definitely didn't fit into the 45 min window that we had. He/she herself vaguely acknowledged it was a hard question. After 10 mins of try, it was followed by another in-depth SQL question.

    It looked like they needed super analyst who could crack all kinds of in-depth data problems in span of minutes. I couldn't imagine working with somebody who had unrealistic expectations like this. I was happy when I got a call from there HR that they didn't pursue it. HR team though is super nice and persuasive and do a good job in profile matching. Just that Netflix's expectations are way out there and a geeky few will fit into that category.

    Application

    I applied through an employee referral. The process took 1+ week. I interviewed at Netflix (Los Gatos, CA (US)).

    Interview

    They move quite fast. One phone interview with the recruiter, and another detailed one with the hiring manager. Two onsite interviews with around 4 people first time (data scientists/engineers) and 3 people (higher level execs) second time. A mix of product, business, analytical and stats questions. Stats questions mostly revolved around A/B testing: hypothesis testing, etc. A couple easy-medium SQL questions. Analytical question included a hypothetical problem to analyze, metrics to evaluate product performance, etc. Higher level executives mostly focused on background and past experience.

    Interview Questions

    • Toughest question was not technically tough, but helping a non-technical exec understand some technical concepts.   Answer Question

    Easy Interview

    Application

    I applied through a recruiter. The process took 3 days. I interviewed at Netflix in December-2011.

    Interview

    I really thought the interview went well. Or so I thought. The director was impressed so was the manager and recruiter. Netflix is expanding into other markets and they like the experiences I have.

    The position is with the analytics dept, which is more horizontal than vertical. Would have loved to work in a dept like that.

    I have a lot of experiences with rec eng/sys and I seriously thought that I had a chance. Come to think of it, I feel that they are prying for what I do in my current company, ie methods, algorithms etc.

    Ideas are dime and a dozen. Good thing is I have more in the bag.
