In this section, we’ll review the various interview questions that might be asked during a Data Engineer interview at EAB. The interview process will likely assess your technical skills, problem-solving abilities, and your capacity to work collaboratively with various stakeholders. Be prepared to demonstrate your knowledge of data engineering principles, SQL proficiency, and your experience with data modeling and schema design.

Technical Skills

1. Can you explain the differences between ROW_NUMBER, RANK, and DENSE_RANK in SQL?

Understanding these SQL functions is crucial for data manipulation and analysis.

How to Answer

Discuss the definitions and use cases for each function, emphasizing their differences in handling duplicate values.

Example

"ROW_NUMBER assigns a unique sequential integer to rows within a partition, RANK gives the same rank to duplicate values but skips subsequent ranks, while DENSE_RANK also gives the same rank to duplicates but does not skip any ranks. This distinction is important when sorting data and ensuring accurate reporting."

2. Describe your experience with ETL processes. What tools have you used?

ETL (Extract, Transform, Load) processes are fundamental in data engineering.

How to Answer

Highlight your hands-on experience with ETL tools and the specific processes you have implemented.

"I have worked extensively with Apache NiFi for data ingestion and transformation, and I have also used Talend for building ETL pipelines. My experience includes extracting data from various sources, transforming it to meet business requirements, and loading it into data warehouses."

3. How do you approach debugging a SQL query that is not returning the expected results?

Debugging skills are essential for a Data Engineer.

How to Answer

Explain your systematic approach to identifying and resolving issues in SQL queries.

Example

"I start by reviewing the query structure and checking for syntax errors. Then, I run the query in parts to isolate the issue, examining the data returned at each step. I also ensure that the joins and conditions are correctly applied to avoid unexpected results."

4. Can you walk us through a data modeling project you have worked on?

Data modeling is a key responsibility for a Data Engineer.

How to Answer

Discuss the project scope, your role, and the outcomes of the data model you created.
