A Software Engineer at Pacific Gas and Electric (PG&E) plays a critical role in building, maintaining, and modernizing the digital infrastructure that powers northern and central California. Unlike standard tech companies, software engineering here sits at the vital intersection of advanced software development and critical physical infrastructure. The applications and systems you build, integrate, and support directly impact the safety, reliability, and clean energy delivery for over 16 million people.

In this role, you will work on complex, high-impact problem spaces that range from grid modernization and asset management to real-time outage tracking and geographic information systems (GIS). You will collaborate closely with cross-functional teams, including electrical engineers, grid operators, data scientists, and project managers, to translate physical utility challenges into scalable software solutions. Your work ensures that the control systems, automation scripts, and enterprise applications running PG&E’s grid remain secure, resilient, and highly available.

Preparing for this position requires an understanding that software quality at PG&E is directly tied to operational safety and public welfare. You are not just writing code; you are engineering systems where reliability is measured in continuous power delivery and community safety. Candidates who succeed are those who can balance technical rigor with a deep appreciation for structured processes, safety-first engineering principles, and collaborative problem-solving.

The questions you will face during the PG&E hiring process are designed to evaluate both your technical competence and your behavioral alignment with the company's core values. These questions are drawn from real interview experiences and represent common patterns you should prepare for.

Behavioral & STAR Questions

These questions assess your past experiences, interpersonal skills, and ability to handle professional challenges. PG&E heavily utilizes the STAR (Situation, Task, Action, Result) method to grade these responses.

• Describe a situation where a project or task did not turn out as planned. What did you do, and what was the outcome?
• Tell me about a time when you and a coworker did not see eye-to-eye. How did you resolve the conflict and reach a conclusion?

Successfully interviewing for a Software Engineer position at PG&E requires a balanced preparation strategy. You must demonstrate both technical capability and strict alignment with the company's structured evaluation criteria.

STAR Methodology Mastery – PG&E interviewers use highly structured evaluation sheets where your answers are scored based on how clearly you define the Situation, Task, Action, and Result. You must practice structuring your past experiences into this framework, ensuring you place significant emphasis on the specific actions you took and the quantifiable results of those actions.

Technical & Analytical Competency – You must be ready to discuss system architecture, scripting, and integration patterns. Depending on the specific team, this may also include demonstrating knowledge of utility-specific concepts such as GIS mapping systems, electrical distribution principles, or infrastructure automation.

Safety-First Orientation – Every candidate must show an active commitment to safety. You should prepare concrete examples of how you have identified, mitigated, and communicated risks—whether physical, operational, or cybersecurity-related—in your previous work environments.

Collaboration & Stakeholder Management – Because PG&E operates as a massive, interconnected utility, you will frequently interact with non-technical stakeholders. You must demonstrate the ability to translate complex technical concepts into clear, actionable business language and show how you build consensus across diverse teams.

The interview process at Pacific Gas and Electric is thorough, structured, and typically takes between four to eight weeks from your initial application to a final decision. The company prioritizes a highly standardized evaluation process to ensure fairness and alignment with regulatory standards.

The journey begins with an online application and a screening questionnaire. For many technical roles, you may also be asked to complete pre-employment tests, such as the Physical Test Battery (PTB) or a Technical Test, which assess basic mathematical, analytical, and logical problem-solving abilities. Once these preliminary stages are cleared, you will proceed to a virtual or on-site panel interview.

The panel interview typically consists of two to four interviewers, including the hiring manager, peer engineers, and subject matter experts. This round is highly structured; the panel will ask a set of pre-determined behavioral and technical questions, taking detailed notes on your responses. The interview concludes with an opportunity for you to ask questions about the team and the role's expectations.

The timeline above outlines the typical progression from your initial application to the final offer stage. Candidates should use this timeline to pace their preparation, ensuring they focus heavily on STAR-based behavioral preparation in the weeks leading up to the panel interview, while maintaining a steady review of core technical concepts.

To excel in the PG&E interview, you must understand the specific domains where you will be evaluated. The panel will look for a blend of structured communication, system-level technical knowledge, and analytical problem-solving.

The STAR Behavioral Framework

Behavioral evaluation is the core of the PG&E interview process. The interviewers are trained to look for specific behavioral indicators and will score your answers based on how well you follow the STAR format.

Be ready to go over:

• Action-oriented ownership – Clearly explaining the specific steps you personally took, rather than speaking generally about what "the team" did.
• Quantifiable results – Ending every story with a clear, measurable outcome (e.g., "reduced deployment time by 20%," "prevented a system outage").
• Conflict and change management – Demonstrating how you professionally navigate disagreements and adapt to shifting priorities.

Example scenarios to prepare:

• "Tell me about a time you had to make a difficult decision with limited data."
• "Describe a situation where you had to influence a stakeholder who disagreed with your technical approach."

Systems Infrastructure & Integration

For Software Engineer roles, PG&E values candidates who understand how software interacts with the underlying infrastructure, operating systems, and network environments.

Be ready to go over:

• Scripting and Automation – Writing scripts (e.g., PowerShell, Python, Bash) to automate deployments, system monitoring, and data migrations.
• Enterprise Environments – Managing software performance and security across Windows and Linux server environments.
• API and Integration Design – Connecting modern web applications with legacy databases and proprietary utility systems.
• Advanced concepts – Understanding network security protocols, firewall configurations, and active directory integrations in highly secure utility networks.

Example questions:

• "How would you design a script to automatically verify system health and push updates to multiple client machines simultaneously?"
• "Describe your approach to integrating a modern web portal with a legacy mainframe database."

Analytical Logic & Problem Solving

Rather than purely focusing on abstract algorithm puzzles, PG&E often evaluates your logical thinking through real-world "what-if" scenarios and analytical exams.

Be ready to go over:

• Logical troubleshooting – Systematically isolating faults in a complex, multi-tiered application environment.
• Data flow analysis – Mapping out how data moves through various subsystems and identifying potential bottlenecks or points of failure.
• Physical-digital integration – Understanding how software commands translate to physical actions in the grid or substation environments.

Example scenarios:

• "If a critical data sync between our mapping system and the field operator application fails, what are the first three things you investigate?"
• "Walk us through how you would test a new software control module before deploying it to live substation hardware."

As a Software Engineer at Pacific Gas and Electric, your day-to-day work will directly support the operational readiness and safety of the utility grid. You will be responsible for a variety of critical technical tasks.
