PG&E Software Engineer interview questions & guide 2026

The interview questions at PG&E are highly structured and standardized. Because many engineering positions are subject to strict corporate and union guidelines, panels frequently ask a pre-approved, scripted set of questions to ensure fairness and consistency across all candidates.

The questions generally fall into three distinct categories: Safety and Compliance, Structured Behavioral, and Systems & Infrastructure.

Safety and Compliance

As a utility provider, safety is the foundational core value of PG&E. You must be prepared to answer a safety-focused question as the very first prompt in your panel interview.

• Describe a safety hazard or risk you noticed in your previous workplace. What immediate actions did you take to resolve it?

Preparing for an interview at PG&E requires a different strategy than preparing for a typical consumer tech company. You must balance technical competence with a highly structured communication style.

Key evaluation criteria include:

Safety Leadership – You must demonstrate an active, proactive commitment to safety in all aspects of your work. This means showing that you do not cut corners, that you speak up when you identify risks, and that you understand the real-world safety implications of the software you build.

STAR Method Mastery – PG&E interviewers grade candidates on a strict rubric. If you do not clearly define the Situation, Task, Action, and Result in your behavioral answers, you will lose points, regardless of how impressive your experience is.

IT/OT Domain Knowledge – You should understand how software interacts with physical systems. Showing an appreciation for grid operations, hardware integration, or enterprise infrastructure deployment will immediately set you apart.

Resilience and Adaptability – Utility environments are highly regulated and can change rapidly due to external events. Interviewers want to see that you can remain calm, structured, and collaborative under pressure.

The interview process at PG&E is thorough, structured, and highly regulated. Because of the company's size and compliance requirements, the process can move more slowly than in the private tech sector, often taking anywhere from four weeks to two months from your initial application to a formal offer.

For many roles, especially entry-level or specialized engineering positions, you will first be required to pass pre-employment tests. These typically include the Physical Test Battery (PTB) or a specialized Technical Test. The math portion of these tests often forbids the use of calculators, focusing on your ability to compute fractions, decimals, and basic algebra quickly and accurately. The technical components assess basic physics principles, diagram interpretation, and spatial problem-solving.

Once you pass the required exams, you will move to the interview stages. The primary interview is almost always a structured panel interview consisting of two to five interviewers, including hiring managers, senior engineers, and HR representatives. This panel is highly conversational but strictly follows a pre-scripted list of questions.

The visual timeline above outlines the typical progression of the PG&E hiring pipeline. Candidates should prepare for a structured journey where passing the initial pre-employment testing is a mandatory gateway before any conversations with the engineering team can occur. Be sure to budget your time and energy accordingly, as the gap between stages can sometimes span several weeks.

To excel in the PG&E software engineering interview, you must understand the specific areas where the panel will focus their evaluation.

Behavioral Excellence (The STAR Method)

This is the most critical non-technical evaluation area. PG&E relies heavily on structured behavioral interviews to ensure cultural alignment and operational discipline. The panel will take detailed notes on everything you say, mapping your answers directly to internal rubrics.

Be ready to go over:

• Conflict Resolution – Concrete examples of resolving professional disagreements constructively.
• Overcoming Technical Setbacks – How you handle system failures, bugs, or project delays.
• Stakeholder Management – Translating technical concepts for non-technical operations staff or business leaders.

Advanced concepts (less common):

• Negotiating project scope with union representatives or compliance auditors.
• Managing long-term legacy system migrations without disrupting daily utility operations.

Example scenarios:

• "Tell me about a time you had to defend a technical decision to a supervisor who disagreed with your approach."
• "Describe a situation where you had to quickly learn a legacy system or proprietary tool to solve an urgent issue."

Safety and Risk Mitigation

At PG&E, safety is not a generic talking point; it is a operational mandate. Your interviewers will evaluate your ability to identify, escalate, and mitigate risks, both in physical environments and software deployment pipelines.

Be ready to go over:

• Risk Identification – Recognizing potential single points of failure in system architectures.
• Compliance and Standards – Adhering to strict utility regulations and data security standards.
• Proactive Mitigation – Speaking up when a process or deployment plan poses a risk to system stability.

Advanced concepts (less common):

• Implementing cyber-physical security protocols for critical infrastructure.
• Designing fail-safe mechanisms in software that controls physical grid assets.

Example scenarios:

• "Describe a time when you noticed a process or system vulnerability that others had overlooked. How did you address it?"
• "How do you ensure that your software deployments do not introduce operational risks to critical, active systems?"

Systems, Scripting, and Infrastructure

While some software roles at PG&E involve modern web development, many focus on system integration, automation, and infrastructure support. You must demonstrate a strong understanding of how to build, deploy, and manage applications in robust enterprise environments.

Be ready to go over:

• Enterprise Deployment – Pushing software across vast, distributed client networks.
• Automation Scripting – Utilizing PowerShell, Bash, or Python to streamline system administration.
• IT/OT Integration – Bridging the gap between software applications and physical utility hardware (such as PLCs, SCADA, or GIS).

Advanced concepts (less common):

• Designing software architectures that interface with electrical distribution and power systems.
• Conducting load flow analysis or integrating telemetry data from grid sensors.

Example scenarios:

• "Walk us through how you would write and test a script designed to deploy a critical patch to thousands of Windows clients."
• "How do you approach designing system architecture when you have to integrate modern APIs with decades-old legacy databases?"

As a Software Engineer at PG&E, your day-to-day work will be highly collaborative and deeply integrated with the company's operational needs. You will not write code in a vacuum; instead, you will work closely with cross-functional teams to solve complex infrastructure challenges.

Your primary responsibilities will center on:

• Application Development and Integration – Designing, writing, and maintaining robust software solutions that support grid operations, customer service, and asset management.
• Infrastructure Automation – Developing scripts and tools to automate system configurations, application deployments, and patch management across both server and client environments.
• Collaboration with Field Operations – Partnering with field engineers, control center operators, and mapping specialists to ensure that software tools meet real-world operational demands.
• Legacy System Modernization – Safely refactoring and upgrading legacy codebases to improve security, performance, and compatibility with modern cloud platforms.
• System Monitoring and Support – Ensuring high availability of safety-critical applications through proactive monitoring, troubleshooting, and rapid incident response.

Q: How technical are the software engineering interviews at PG&E? A: The technical depth varies significantly by team. Some interviews focus almost entirely on behavioral questions, system architecture, and scripting logic, with no actual live coding. Other teams may require a basic coding assessment or domain-specific technical questions related to power systems, PLCs, or infrastructure deployment.

Q: What is the pre-employment testing process? A: For many roles, you must pass the PTB (Physical Test Battery) and a Technical test before interviewing. The PTB tests basic math (without a calculator), while the Tech exam covers basic physics, diagram reading, and logical word problems. These are designed to ensure foundational analytical competency.

Q: How important is the STAR method in the interview? A: It is absolutely critical. PG&E interviewers use standardized scorecards provided by HR. If you do not structure your answers using the STAR format (Situation, Task, Action, Result), the panel will have difficulty grading your responses, which can significantly lower your overall score.

Q: What is the company culture like for software engineers? A: The culture is highly structured, collaborative, and stability-focused. Because the work involves critical public infrastructure, there is a strong emphasis on compliance, safety, and thorough planning over the "move fast and break things" mentality common in consumer tech.

Q: Does PG&E hire contractors, and what is that process like? A: Yes, PG&E hires a significant number of software engineers and analysts as contractors through external agencies. The interview process for contract roles is typically faster, often consisting of a single interview with the hiring manager rather than a full panel.

To maximize your chances of success, keep these practical, insider tips in mind during your preparation:

• Prepare your safety story in advance: You will be asked about safety. Have a compelling, real-world example ready of a time you identified a risk (physical or digital) and took action to resolve it.

• Brush up on basic math: If your role requires the PTB exam, practice mental math, fractions, decimals, and long division. Not having a calculator can catch many modern software engineers off guard.
• Be ready for a quiet panel: PG&E interviewers are often required to take exhaustive notes during your answers. Do not be discouraged if they do not provide immediate feedback or maintain continuous eye contact; they are capturing your details to grade you fairly.

• Show respect for legacy systems: Much of the utility grid relies on robust, older technology. Avoid criticizing legacy systems; instead, demonstrate an understanding of why they exist and how to safely integrate or modernize them.
