Problem-solving ability – Interviewers look for your ability to break down ambiguous, high-stakes security problems. Focus on communicating your thought process clearly, demonstrating how you weigh risks, costs, and operational impact.

Leadership and Influence – Security is a team effort. You will be evaluated on your ability to communicate effectively with diverse stakeholders and influence others to adopt security best practices. Use the STAR method (Situation, Task, Action, Result) to frame your experiences.

The interview process at PG&E is designed to evaluate both your technical acumen and your alignment with the company’s mission. You should expect a series of interactions that test your ability to work within a multidisciplinary environment. The process is often structured to include multiple stakeholders, reflecting the reality that security is a cross-departmental responsibility.

The visual timeline above illustrates the typical progression from initial screening to final interviews. Use this to pace your preparation, ensuring you have enough time to review both technical concepts and your personal project history before moving into the later, more collaborative stages.

Security Infrastructure & Architecture

This area is fundamental to the role. We evaluate your ability to design systems that are secure by default and resilient against sophisticated attacks.

Be ready to go over:

• Network Security – Understanding firewalls, IDS/IPS, and segmenting critical systems.
• Identity and Access Management (IAM) – Principles of least privilege and robust authentication mechanisms.

As a Security Engineer, you will be responsible for the end-to-end security posture of assigned systems. This involves active monitoring, proactive threat hunting, and the development of security automation to reduce manual overhead.

Collaboration is central to this role. You will work closely with system administrators, developers, and project managers to ensure that security controls do not impede the reliable delivery of energy services. You will also participate in regular audits and compliance reviews, making documentation and meticulous attention to detail essential parts of your daily workflow.
