Interview questions for data engineers with examples of responses

Seven of the most typical data engineer interview questions are listed here. As you consider your own answers to help you prepare for the interview, go over the explanation and sample responses.

  • Data engineering: What is it?
  • What are the key qualities of a data engineer?
  • Which frameworks and apps are crucial for data engineers?
  • Can you explain the design schemas related to data modeling?
  • Do you consider yourself database- or pipeline-centric?

1. What is data engineering?

Interviewers typically put this question up to check whether you can discuss your field in an intelligible and competent way. When you answer, attempt to offer a general synopsis as well as a brief discussion of how data engineers communicate with colleagues.

Example: “Data engineering powers the collecting and processing of information through a combination of desktop software, mobile applications, cloud-based servers and physical infrastructure. Effective data engineering involves careful development, sturdy pipelines and clever partners. Data engineers are key partners of data scientists, who analyze and utilise the information we collect.”

2. What are the fundamental qualities of a data engineer?

An interviewer might ask this question to discover whether your idea of a skilled professional matches the company’s evaluation. In your answer, outline the talents and qualities that you think are crucial for data engineers. Try to provide particular circumstances in which a data engineer would apply these talents.

Example: “A competent data engineer needs to know how to construct distributed systems and data repositories, create trustworthy pipelines and mix data sources effectively. Data engineers also need to be able to collaborate with team members and colleagues from other departments. To fulfill all of these jobs, a data engineer needs strong math and computational skills, critical thinking and problem-solving skills and communication and leadership capabilities.”

3. Which frameworks and apps are crucial for data engineers?

Hiring managers typically ask this question to assess your comprehension of the major requirements for the position and to find out whether you have essential technical abilities. When you answer, be as descriptive as possible and provide the names of frameworks and applications. Consider noting your experience level with each as well.

Example: “Data engineers have to be knowledgeable in SQL, Amazon Web Services, Hadoop and Python. I am fluent with all of these frameworks and I am also familiar with Tableau, Java, Hive and Apache Spark. I cherish every opportunity to learn new frameworks.”

4. Can you clarify the design schemas related to data modeling?

Hiring teams may quiz you about design schemas as a technique to test your knowledge of the principles of data engineering. When you respond, try your best to convey the notion clearly and concisely.

Example: “Data modeling involves two schemas, star and snowflake. Star schema has dimension tables that are coupled to a fact table. Snowflake schema comprises a similar fact table and dimension tables with snowflake-like layers.”

5. Do you consider yourself database- or pipeline-centric?

Interviewers frequently bring this question up to see whether you have a focus area and if it aligns with the needs of the firm. In your response, provide an honest assessment of your specialization. Try your best to reflect the complete breadth of your technical knowledge and experience, especially if you have the skills for both data engineering specialties.

Example: “Because I normally chose to work for smaller firms, I am a generalist who is equally happy with a database or pipeline focus. Since I specialize in both components, I have complete expertise of distributed systems and data warehouses.”

6. What is the toughest professional obstacle you have conquered as a data engineer?

Hiring managers typically use this question to learn how you solve issues at work. Rather than learning about the intricacies of these issues, they often seek to determine how resilient you are and how you process what you learn from stressful events. When you answer, try using the STAR approach, which entails explaining the scenario, task, action and consequence of the conditions.

Example: “Last year, I functioned as the main data engineer for a project that had insufficient internal support. As a result, my piece of the project ran behind time and I risked disciplinary penalties. After my team missed the first deadline, I took the initiative to meet with the project manager and presented various solutions. Based on my advice, the corporation assigned additional workers to my team and we were able to complete the project successfully within the intended timeline.”

7. As a data engineer, how would you prepare to design a new product?

Hiring teams may quiz you about product development to determine how much you know about the product cycle and the data engineer’s involvement in it. When you respond, highlight some of the ways your knowledge could streamline the development process and some of the questions you would consider to build the greatest possible result.

Example: “As a lead data engineer, I would seek an outline of the entire project so I can comprehend the complete scope and the unique requirements. Once I know what the stakeholders want and why, I would outline various situations that might emerge. Then I would utilize my understanding to begin constructing data tables with the proper amount of granularity.”
