In this section, we’ll review the various interview questions that might be asked during a Software Engineer interview at Duke Energy Corporation. The interview process will likely focus on both technical and behavioral aspects, assessing your problem-solving skills, teamwork, and ability to adapt to the company's culture. Be prepared to discuss your past experiences, technical knowledge, and how you approach challenges in a collaborative environment.

Technical Skills

1. What is your experience with cloud-native software engineering best practices?

Understanding cloud-native principles is crucial for this role, as Duke Energy emphasizes building solutions for cloud environments.

How to Answer

Discuss your familiarity with cloud platforms and how you've applied best practices in previous projects. Highlight specific tools or methodologies you've used.

Example

"I have extensive experience with AWS and Azure, where I implemented microservices architecture to enhance scalability.
