Kimley-Horn Solutions Architect interview questions & guide 2026

The interview process at Kimley-Horn is highly professional and conversational, yet rigorous in its assessment of your technical depth and problem-solving ability. Questions are designed to gauge how you handle real-world infrastructure challenges and communicate technical trade-offs to stakeholders.

System Design & ML-System-Design

These questions test your ability to build scalable, resilient architectures while managing costs and performance.

• How would you design a data lifecycle and archival strategy for a large-scale ArcGIS Enterprise environment to balance storage costs against active user needs?
• If a critical production database is experiencing high latency, what is your step-by-step process for identifying the bottleneck and implementing a fix?

Preparation for this role should focus on your ability to connect deep technical expertise with business outcomes. Kimley-Horn values professionals who can see the "big picture" of the infrastructure lifecycle.

Technical Depth – You must demonstrate mastery over Esri ecosystems and database administration. Interviewers will look for your ability to discuss not just the "how," but the "why" behind your architectural decisions.

Strategic Communication – You will often act as a translator between technical teams and leadership. Be prepared to explain how your architectural choices mitigate business risk or improve organizational efficiency.

Mentorship & Influence – As a senior member of the team, your ability to elevate those around you is critical. Use the STAR method (Situation, Task, Action, Result) to provide concrete examples of how you have guided teams through technical change.

The interview process at Kimley-Horn is known for being welcoming and efficient, emphasizing a mutual fit between the candidate and the team. You can expect a professional, conversational tone, even during highly technical discussions. The process typically begins with a recruiter screen to establish your background and interest, followed by interviews with team members from various offices who will evaluate your technical portfolio and your approach to complex problem-solving.

The visual timeline above highlights the progression from initial screening to deeper technical assessments. Use this to pace your preparation; ensure you are ready to discuss both your high-level architectural philosophy and your specific hands-on experience with Azure and ArcGIS components early in the process.

Infrastructure & Scalability

You are being evaluated on your ability to manage a 10,000+ user environment. Strong candidates demonstrate a "preventative" mindset, focusing on monitoring and automation before issues arise.

Be ready to go over:

• Capacity Planning – How to forecast storage and compute needs for a growing organization.
• Migration Strategy – Managing the downtime and risks associated with major platform shifts.

As a Solutions Architect, your day-to-day work involves owning the long-term technical roadmap for the organization’s ArcGIS Enterprise environment. You are the architect of the platform's health, which means you spend significant time planning infrastructure migrations, designing archival strategies, and ensuring that the platform can scale to meet the needs of thousands of users.

Collaboration is essential; you will partner with IT governance, security teams, and fellow engineers to ensure that system-level changes are seamless. You also serve as the senior technical escalation point, meaning you are the one the team turns to when production issues become critical or when data problems appear insurmountable.

A successful candidate for the Solutions Architect position at Kimley-Horn is a blend of a seasoned administrator and a strategic thinker.

• Must-have skills: 8+ years of Esri ArcGIS Enterprise administration, deep PostgreSQL performance tuning expertise, and experience leading at least one full-lifecycle infrastructure migration.
• Nice-to-have skills: Esri certifications, experience building data governance programs from scratch, and familiarity with enterprise-grade monitoring tools like Datadog or Splunk.
• Soft skills: Ability to mentor junior staff, excellent problem-solving skills at the architecture level, and a proactive approach to continuous improvement.

Q: How difficult are the technical interviews? A: The technical interviews are challenging but fair. They focus on real-world scenarios rather than "gotcha" questions, so focus on your actual experience with infrastructure and problem-solving.

Q: Is there a specific focus on coding? A: Yes, but it is applied. You should be comfortable writing Python/ArcPy scripts for automation, reporting, and governance enforcement.

Q: How much does company culture play a role? A: Kimley-Horn places a high premium on collaboration and employee development. Demonstrating that you are a team player who is willing to share knowledge is just as important as your technical skills.

• Own your projects: When discussing past work, clearly articulate your specific role in migrations or architectural changes. Use "I" instead of "we."
• Focus on the "Why": In system design, always explain the reasoning behind your choice of technology or architecture.
• Prepare for the "Consultant" mindset: You are working for a firm that serves clients; show that you understand how your technical decisions impact client success.
• Be ready for the "Human" element: Kimley-Horn is known for its culture. Be prepared to talk about why you want to work for a company that values its people.
