Experience and Background

1. Describe a time when you had to take leadership in a project.

Chevron values leadership and teamwork, and they will want to know how you can guide a team effectively.

How to Answer

Use the STAR method to structure your response, focusing on the situation, task, action, and result. Highlight your leadership style and how it contributed to the project's success.

Example

“In my last internship, I led a team of three on a data migration project. We faced tight deadlines, so I organized daily stand-up meetings to track progress and address any blockers. As a result, we completed the migration two days ahead of schedule, which allowed the company to start using the new system sooner.”

Technical Skills

2. What is the difference between SQL and NoSQL databases?

Understanding database types is crucial for a Data Engineer, and this question tests your foundational knowledge.

How to Answer

Explain the key differences in terms of structure, scalability, and use cases. Mention specific scenarios where one might be preferred over the other.

Example
