Srividya Krishnamoorthy
Senior Data Engineer
Placed at:
Interview Kickstart provides a nice, structured way of interview preparation for experienced professionals. I would like to thank each and every mentor from IK for their time and effort. I got multiple FAANG offers from TOP companies that includes Amazon and Facebook. I have joined Facebook as a Senior Data Engineer.
Mike Kane
Lead Data Engineer
Placed at:
I really like the courses. For many working professionals, going through examples and different perspectives are the most valuable. I started interviewing for FB in May, then took IK to study for this specific company. IK was great because its structure helped me really understand each problem in my interview.
Akshay Lodha
Data Engineering & Analytics
Placed at:
The experience with IK was phenomenal, it was totally worth it. After so many years I was interviewing and IK helped me a lot in orienting myself and to get into the rhythm. Had a transition from Goldman Sachs to Facebook. IK mentors guided me and told me not to worry about the preparation part and to focus on upskilling myself. That really made a huge difference.
Anju Mercian
Data Engineering Consultant
Placed at:
The program has been really fantastic. It has given me insights of what I need to study and how to approach problems. The patterns that are taught in IK is something that I really enjoy and have not been taught in my many years of experience in the industry and studying for interviews. The approach is really fantastic. The learning experience was also great. The big support system is also what I really admire about IK.

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.
1
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.
