In this section, we’ll review the various interview questions that might be asked during a Data Engineer interview at Acxiom. The interview process will likely focus on your technical skills, experience with data engineering, and your ability to collaborate with cross-functional teams. Be prepared to discuss your past projects, your approach to problem-solving, and your understanding of data technologies.

Technical Skills

1. What is your experience with SQL and how have you used it in your previous projects?

Understanding your SQL proficiency is crucial, as it is a fundamental skill for data engineers.

How to Answer

Discuss specific projects where you utilized SQL for data manipulation, querying, or ETL processes. Highlight any complex queries or optimizations you implemented.

Example

“In my last role, I used SQL extensively to extract and transform data from various sources for our data warehouse. I optimized several queries that reduced processing time by 30%, which significantly improved our reporting capabilities.”

2. Can you explain the difference between ETL and ELT?

This question assesses your understanding of data processing methodologies.

How to Answer

Clearly define both terms and explain when you would use each approach, providing examples from your experience.

Example

“ETL stands for Extract, Transform, Load, where data is transformed before loading into the target system. ELT, on the other hand, loads raw data first and then transforms it. I prefer ELT for big data scenarios where we need to leverage the processing power of cloud platforms like AWS or Azure.”

3. Describe a data pipeline you have built. What challenges did you face?

This question evaluates your hands-on experience with data engineering.

How to Answer

Outline the project, the technologies used, and the specific challenges you encountered, along with how you overcame them.
