What Does a Netflix Data Engineer Do?

A data engineer is responsible for building systems that help in the collection, management, and conversion of raw data into comprehensible and useful information. The information is then analyzed by data scientists and business analysts. 

The main goal of data engineers is to make data as accessible as possible for the organization so that they can analyze it. Then the information is used to optimize and elevate the company's performance. This is what’s tested in the Netflix data engineer interview process.

At Netflix, in order to maximize the impact of this research, they don’t centralize the research into a different organization. What they do is they have several teams that pursue research and work with business teams, engineers teams, as well as other researchers.  

Netflix Data Engineer Interview Process

The Netflix data engineer interview process is broadly divided into three stages:

  1. Initial screen round
  2. Technical screen round
  3. On-site interviews

Initial Screen Round

In this round, the recruiter will call you for a 30-minute interview. In this initial stage of the Netflix data engineer interview process, the recruiter will go through your resume with you. The recruiter will ask questions related to your past experiences, skills, and projects.

Netflix has highly-specialized and technical recruiters. So in this call, your general communication skills will also be tested. Further, the role and responsibilities will be explained.

Technical Screen Round

This round lasts around 45 minutes, and you’ll be asked technical questions on topics such as SQL, analytics, machine learning, and algorithms. So before appearing for this round of the Netflix data engineer interview process, prepare accordingly. 

Here are some sample questions:

  • Which is the best way to present ML results to the stakeholders?
  • Why would you choose S3 versus a NoSQL database?
  • Define shuffle sort.

On-site Interviews

The final stage of the Netflix interview process for data engineers is divided into two parts, with a lunch break in between. These are one-on-one interviews with 6 to 7 interviewers that include data engineer team members, team managers, and a product manager.

The on-site interviews will test you on multiple concepts such as SQL, analytics, machine learning, and algorithms. There will also be a behavioral interview where they’ll determine whether you’re a cultural fit or not.

Since this is an engineering role, the interviews will focus more on engineering, machine learning, and deep learning interview questions. 

Data Engineer Interview Questions

We’ve listed some sample interview questions that you can prepare for to crack the Netflix data engineer interview process below:

  1. How will you transform unstructured data into structured data?
  2. What is the process of validating a data migration from one data source to another?
  3. Define Hadoop. How is it connected to Big Data? 
  4. Are you more database-centric or pipeline-centric?
  5. Talk about a distributed system you built and how you engineered it?
  6. For proficient data processing, which Python libraries will you use?
  7. Talk about your experience using PostgreSQL or other RDBMS.
  8. Do you have an understanding of NoSQL databases? Elaborate on it. 
  9. Do you know how to build and maintain data pipelines using Kafka (or similar)?
  10. How will you diagnose a performance issue in a Spark job?
  11. How will you design a video streaming service such as YouTube or Netflix?

Preparing for these types of interview questions will surely help you get ready for your Netflix data engineer interview.
