Lockton Companies Software Engineer interview questions & guide 2026

The interview questions you will encounter at Lockton Companies are designed to evaluate both your foundational programming knowledge and your ability to apply technical concepts to real-world business challenges. While the exact questions will vary depending on your team and seniority level, historical interview data reveals a clear pattern: the company prioritizes practical coding, database design, and behavioral alignment over abstract, hyper-theoretical computer science puzzles.

Technical & Core Programming

These questions assess your understanding of fundamental software engineering principles, object-oriented design, and database management.

• Explain the difference between an abstract class and an interface, and when you would use each.
• How do you optimize a slow-running SQL query, and what is the role of indexing in database performance?

Preparing for an interview at Lockton Companies requires a balanced approach. You must demonstrate strong technical foundations while showcasing the soft skills necessary to thrive in a relationship-driven business.

Technical Competence – You need a strong grasp of backend development concepts, database design, and API development. Be prepared to discuss your experience with enterprise-grade languages (such as C#/.NET or Python) and relational databases (such as SQL Server).

Domain Adaptability – You do not need to be an insurance expert on day one, but you must show a willingness to learn the business domain. Showing an interest in actuarial science, financial risk, or property data modeling will set you apart from other candidates.

Collaborative Communication – Software engineers at Lockton Companies work closely with business analysts, brokers, and clients. You must be able to explain complex technical architectures in simple, business-friendly terms.

Cultural Alignment – Lockton Companies is famous for its entrepreneurial, service-oriented culture. You should demonstrate a proactive, self-starting attitude and a genuine desire to build solutions that make life easier for internal teams and clients.

The interview process for a Software Engineer at Lockton Companies is known for being remarkably smooth, fast, and structured. Unlike many tech giants that subject candidates to grueling multi-day loops, Lockton Companies focuses on an efficient evaluation process that respects the candidate's time while thoroughly assessing both technical capability and team fit.

The process typically consists of two distinct stages. The initial stage is a virtual screening, usually conducted via Microsoft Teams, which focuses on your career background, high-level technical experience, and alignment with the role's core responsibilities. If you pass this screen, you will move to the second and final stage. Depending on your location, this final round is conducted either in-person at one of their regional offices (such as London, Kansas City, or Minneapolis) or as a deeper virtual panel with hiring managers and directors.

Throughout the process, the hiring team places a strong emphasis on practical experience and cultural chemistry. They want to understand how you approach real-world software development challenges and how comfortably you will integrate into their close-knit, entrepreneurial engineering teams.

The timeline module above outlines the typical progression of the Lockton Companies hiring loop. Candidates should use this timeline to pace their preparation, focusing first on high-level project walkthroughs and transitioning to deeper architectural and cultural preparation for the final stage. While the process is streamlined, the expectations for technical quality and cultural alignment remain high at every step.

To succeed in the Lockton Companies hiring process, you must understand exactly how you will be evaluated across key technical and professional dimensions.

Practical Software Engineering & Architecture

This area evaluates your ability to write clean, maintainable, and scalable code. Interviewers want to see that you understand modern software design patterns and can build robust systems.

Be ready to go over:

• Object-Oriented Design – Solid understanding of SOLID principles, dependency injection, and common design patterns.
• API Development – Best practices for designing RESTful APIs, versioning, and secure authentication.
• Database Design – Relational database normalization, indexing strategies, and writing efficient SQL queries.
• Advanced concepts (less common) – Microservices architecture, cloud infrastructure integration (Azure/AWS), and containerization using Docker.

Example questions or scenarios:

• "Walk me through the architecture of a web application you recently built. What design patterns did you use, and why?"
• "How would you refactor a legacy monolithic application to make it more modular and testable?"

Business Logic & Domain Integration

As a Software Engineer, you will write systems that calculate financial risk, model properties, or automate actuarial tasks. This evaluation area tests your ability to translate complex logic into code.

Be ready to go over:

• Data Processing – Handling, parsing, and validating large datasets from diverse sources.
• Algorithm Implementation – Translating mathematical formulas or business rules into performant algorithms.
• Testing & Accuracy – Strategies for unit testing and verifying the accuracy of financial or analytical calculations.

Example questions or scenarios:

• "How would you design a system to validate that an actuarial calculation engine is returning 100% accurate results after a code deployment?"
• "Describe how you would handle a scenario where an external data feed of property valuations suddenly changes its format."

Collaboration & Culture Fit

This area evaluates your communication style, your ability to work in cross-functional teams, and your alignment with the core values of Lockton Companies.

Be ready to go over:

• Stakeholder Communication – Translating technical concepts for non-technical business partners.
• Teamwork & Mentorship – How you support your peers, conduct code reviews, and contribute to a positive engineering culture.
• Adaptability – Handling changing business priorities and ambiguous requirements in a fast-paced environment.

Example questions or scenarios:

• "Tell me about a time you had to build a feature based on highly ambiguous requirements. How did you proceed?"
• "How do you handle constructive feedback during a code review?"

As a Software Engineer at Lockton Companies, your day-to-day responsibilities will be highly dynamic and deeply connected to the business. You will write clean, well-tested code to implement new features and maintain existing applications, ensuring high availability and performance.

Collaboration is a core component of this role. You will work closely with product managers, business analysts, and domain experts (such as actuaries and property risk engineers) to gather requirements and translate business needs into technical specifications. You will participate in daily stand-ups, sprint planning, and collaborative design sessions.

Additionally, you will play an active role in maintaining system health. This includes optimizing database queries, setting up robust logging and monitoring, and troubleshooting production issues. You will also participate in code reviews, providing constructive feedback to your peers and helping to maintain high standards of code quality across the team.

To be competitive for a Software Engineer position at Lockton Companies, you should possess a strong blend of technical expertise and professional skills.
