At Applied Systems, a Software Engineer does more than just write code; you are the engine behind the digital transformation of the insurance industry. We are the world’s largest provider of agency management systems and insurtech software, and your work directly impacts how millions of insurance policies are quoted, sold, and managed. Whether you are working within our EZLynx division on real-time rating, our Indio team on digital data collection, or our core Platform Engineering groups, your contributions make us indispensable to our customers.
You will join a culture that views winning as a team sport. Our engineers drive the full software development lifecycle—from architectural design and feature implementation to automated testing and production monitoring. You will tackle complex challenges related to SaaS scalability, secure data handling, and API integration. Because we operate in a highly regulated and data-intensive industry, your role requires a balance of innovative problem-solving and an unwavering commitment to software quality and stability.
Getting Ready for Your Interviews
Preparing for an interview at Applied Systems requires a clear understanding of our technology landscape and our values. We look for engineers who are technically versatile but also deeply collaborative. You should approach your preparation with a focus on practical application rather than abstract theory.
Technical Fluency within Your Stack We hire for specific technology tracks (primarily .NET/C#/Angular or Python/Django/PostgreSQL). Interviewers evaluate your depth of knowledge in your specific stack. You must demonstrate not just how to use a framework, but how to architect scalable solutions within it.
Commitment to Quality and Automation We do not view testing as a separate phase; it is integral to engineering. You will be evaluated on your experience with automated test systems (Unit, Integration, E2E) and your ability to author maintainable, clean code. Expect questions on how you ensure stability in a CI/CD environment.
Collaborative Problem Solving As a remote-first and distributed organization, communication is paramount. We assess how you handle code reviews, how you mentor junior engineers (especially for Senior roles), and how you navigate technical debates. We look for "teammates," not just individual contributors.
Interview Process Overview
The interview process at Applied Systems is designed to be thorough yet respectful of your time. It typically begins with a recruiter screening to align on your experience, location (remote suitability), and interest in the specific division (e.g., EZLynx, Indio, or Core). Following this, you will proceed to a technical screening with a hiring manager or team lead. This conversation focuses on your high-level technical background and your alignment with our "indispensable teammate" culture.
The core of the evaluation involves deep-dive technical rounds. Depending on the team, this may include live coding sessions, system design discussions, or a practical review of your past projects. Unlike companies that focus heavily on "LeetCode" style puzzles, our technical rounds often mirror real-world tasks you would encounter on the job—such as designing a REST API, debugging a React/Angular component, or optimizing a SQL query. We want to see how you write production-ready code and how you reason through architectural trade-offs.
Final rounds often involve meeting cross-functional partners, such as Product Managers or other Engineering leads, to assess your ability to translate business requirements into technical solutions. Throughout the process, expect an emphasis on how you work in a team, how you handle feedback during code reviews, and your passion for learning new tools.
The timeline above illustrates the typical flow from application to offer. Use this to pace your preparation; ensure you have refreshed your core stack knowledge before the technical screen and practiced system design concepts before the deep dive rounds. Note that the specific technical questions will vary significantly based on whether you are interviewing for a .NET role or a Python role.
