Sunrun Business Analyst interview questions & guide 2026

Expect a mix of technical tests and behavioral inquiries. The questions are designed to reveal how you think and how you would fit into the Sunrun ecosystem.

Technical & Data Analysis

These questions test your "hard" skills and your ability to work with the tools of the trade.

• "Explain the difference between a VLOOKUP and an INDEX-MATCH and when you would use each."
• "How would you handle a dataset where 20% of the entries are missing key values?"

Preparation for a Business Analyst role at Sunrun requires a dual focus: technical mastery of data tools and a deep alignment with our corporate mission. We look for candidates who can demonstrate not only that they can perform the analysis, but also that they understand the "why" behind the data.

Role-related knowledge – You must demonstrate a high level of proficiency in data manipulation and analysis tools. At Sunrun, this primarily manifests as advanced Excel skills, including the ability to manage large datasets and build functional models. Interviewers evaluate your ability to transform raw data into a narrative that supports business objectives.

Problem-solving ability – We value a structured approach to complex challenges. You will be assessed on how you break down business problems, identify key variables, and propose scalable solutions. Demonstrating a logical flow from problem identification to data analysis and final recommendation is essential.

Mission Alignment & Culture Fit – Sunrun is a mission-driven company. We look for "Sunrunners" who are genuinely enthusiastic about renewable energy and sustainability. Beyond technical skills, we evaluate your communication style, your ability to work cross-functionally, and your resilience in a high-growth, changing environment.

Leadership & Communication – As a Business Analyst, you will often need to present your findings to stakeholders who may not be as data-savvy. Interviewers look for your ability to simplify complex concepts and influence decision-making through clear, confident communication.

The interview process at Sunrun is designed to be comprehensive yet straightforward, ensuring a mutual fit between the candidate and the team. You can expect a process that balances technical validation with behavioral assessments to see how you would integrate into our collaborative culture.

The journey typically begins with a recruiter screen followed by one or more phone interviews with members of the specific team you are applying for, such as Asset Management. These initial conversations focus on your background, your interest in the solar industry, and your high-level technical experience. Following the screens, most candidates will undergo a technical assessment, often centered on an Excel test, to verify core analytical competencies.

The final stage usually involves a series of interviews with various team members and managers. This "onsite" (which may be conducted virtually) is intensive and aims to provide a 360-degree view of the role and the team. You will meet with potential peers and leadership to discuss your problem-solving approach and cultural alignment.

The timeline above outlines the standard progression from initial contact to the final decision. Candidates should use this to pace their preparation, ensuring they are technically sharp for the early assessments and prepared for deeper behavioral and strategic discussions during the multi-interviewer stage.

Data Proficiency & Technical Analysis

This is the bedrock of the Business Analyst role. At Sunrun, we rely on data to manage our assets and predict future performance. You will be tested on your ability to handle data accurately and efficiently.

Be ready to go over:

• Advanced Excel – Mastery of pivot tables, VLOOKUPs/INDEX-MATCH, and complex formulas is mandatory.
• Data Visualization – The ability to create clear, impactful charts and dashboards that communicate trends effectively.

As a Business Analyst at Sunrun, your primary responsibility is to translate data into strategic action. You will spend a significant portion of your time managing and analyzing datasets related to Asset Management, customer accounts, or operational workflows. You will be expected to maintain and improve existing reporting frameworks while developing new models to address emerging business needs.

Collaboration is a daily requirement. You will work cross-functionally with IT, Finance, and Customer Service teams to gather data and ensure that your insights are integrated into broader company initiatives. You are the "truth-seeker" in the room, providing the objective data needed to settle strategic debates and guide the company’s trajectory.

Typical projects might include analyzing the financial performance of specific solar funds, identifying bottlenecks in the installation pipeline, or forecasting long-term maintenance costs for our solar arrays. You will be responsible for creating high-quality deliverables that help senior leadership make informed decisions about where to allocate resources.
