Data Engineer Interview Process Outline

The interview process for Data Engineers typically evaluates your knowledge of core SQL, Big Data, coding, and behavioral concepts. To tackle Data Engineer interview questions asked at FAANG+ interviews, it’s extremely important to know what to expect at these interviews.

Here’s what the Data Engineering interview process at top companies looks like.

1 round of writing SQL queries – 5-6 problems on a dataset (understanding the trade-offs between joins, equivalent queries, and so on) and related Data Engineer interview questions.
1 round based on Python, SQL, and Big Data Frameworks – Writing MapReduce equivalent for SQL/Spark queries, solving programming questions on dictionary manipulations. Data engineering interview questions in this round also test your working knowledge of Hive, Spark, and other NoSQL databases.
2-3 rounds on core Data Engineering concepts – These rounds involve solving Data Modeling and SQL problems, designing an ETL system for a given use case, explaining trade-offs between tools (applicable to senior roles), data optimization, and fine-tuning.
1 behavioral interview round – In this round, you can expect questions related to your job experience, discussions on past projects, and open-ended questions to gauge if you’re a “good fit.”

At top companies, the interview process for Data Engineers is pretty standard. To give you a clearer idea, let’s see what the interview process looks like at top companies.

Amazon Data Engineer Interview Process

Amazon is known to have one of the most challenging interview processes for Data Engineers. The interview essentially evaluates your knowledge of core data structures, algorithms, ML concepts, SQL concepts, and data-oriented design concepts. The interview process at Amazon also has a special Bar Raiser round where you’re evaluated by a specially trained Bar Raiser to see if you’re the right cultural fit at the company.

The interview process consists of:

1 coding round
1-2 design rounds, 1-2 SQL rounds
1 domain-specific round (ETL, Data Modeling, and Data Visualization)
1 behavioral/leadership round and the Bar Raiser round

Learn some tips on How to Prepare for the Amazon Data Engineer Interview.

Facebook Data Engineer Interview Process

The Facebook Data Engineer interview process is similar to the process at Amazon but doesn’t include the Bar Raiser round. You can expect:

Data Engineering Interview Questions on Coding

Given an integer array arr of size n, find all magic triplets in it. A magic triplet is a group of three numbers whose sum is zero.

Given an array of integers, find any non-empty subarray whose elements sum up to zero.

Given an unsorted set of numbers from 1 to N with exactly two of them missing, find those two missing numbers.

For an array of integers and unique values, write a program code to decipher if the sum of any two integers in the array is equal to a given value.

Data Engineering Interview Questions on SQL Queries

You’re given a dataset with information on users who’ve purchased a list of products. Design a dashboard to highlight specific aspects of user behavior.

You’re given a dataset with the number of users visiting an e-commerce site and purchasing a long list of products. Find the top-performing product in the last one hour.

Create DDL (table and foreign keys) for several tables in a provided ERD.

Create a real-time dashboard to return the number of views for a popular video posted online. Also, find how many users didn’t watch the entire length of the video.

You’re given a raw table with information. Use ETL design to create a clear table with neatly distributed information using SQL.

Generic Data Engineering Interview Questions

How would you handle duplicate data points in an SQL query?

For an expected increase in data volume, what steps would you take to add more capacity to the data processing architecture?

For a given array of integers of length n spanning 0 to n with one missing, you have to write a function missing_number that returns the missing number in the array.

For a given list of integers, write a program to find the index where the sum of the left half of the list equals the right half. Return -1 if there is no index satisfying the condition.

When would you use the NumPy library vs. pandas?
