Included Health Backend Engineer interview questions & guide 2026

This module provides the current compensation range for the Senior Software Engineer, Backend position. Use these figures to calibrate your expectations regarding the level of seniority and impact the company anticipates for this role, keeping in mind that total compensation packages may also include equity and benefits.

Our interview process is designed to evaluate both your technical depth and your ability to navigate the complexities of a fast-growing health-tech company. The following questions are representative of the patterns we look for; use them to practice articulating your thought process clearly and concisely.

Technical Proficiency and Infrastructure

These questions probe your hands-on experience with the tools and architectural patterns essential to our stack.

• How do you leverage Docker to ensure consistency across development and production environments?
• Can you explain your process for troubleshooting a performance bottleneck in a high-traffic API?

Preparation at Included Health requires more than just technical memorization; it requires a demonstration of how you think. You should prepare to speak about your past projects with precision, focusing on the "why" behind your technical choices rather than just the "how."

Technical Depth – We evaluate your ability to apply core engineering principles to real-world problems. You should be prepared to discuss your experience with containerization, API design, and data persistence in depth.

Collaborative Problem Solving – Engineering at Included Health is a team sport. We look for candidates who can explain their thought process, accept feedback during coding exercises, and effectively communicate with non-technical stakeholders.

Ownership and Initiative – We value engineers who take responsibility for their code from design to deployment. Be ready to discuss how you have managed projects, handled production incidents, or mentored junior team members.

The interview process at Included Health is rigorous, reflecting the high standards required for our platform. You can expect a series of conversations that move from initial screenings to deep-dive technical sessions. We prioritize a balanced assessment of your coding skills, your architectural thinking, and your cultural alignment with our mission-driven environment.

The process is designed to be transparent but challenging. You will interact with various members of the engineering team, ranging from peers to leadership. We want to see how you handle complex problems under pressure and how you communicate your reasoning. Our philosophy is that the best engineering work comes from collaboration, and our interview stages are structured to mirror that reality.

The visual timeline above outlines the standard progression of our interview stages. Use this to structure your preparation, ensuring you have refreshed your knowledge on system design and coding fundamentals before the later-stage technical rounds.

System Design and Scalability

This area assesses your ability to design resilient, scalable systems that can handle the complexities of healthcare data. We look for a clear understanding of trade-offs when choosing between different architectural patterns.

Be ready to go over:

• Microservices architecture – How to handle service-to-service communication and failure modes.
• Data consistency – Managing transactions across distributed systems.

As a Backend Engineer, your primary responsibility is the development and maintenance of scalable, secure backend services. You will be expected to write clean, maintainable code while actively participating in the design of new features. You will collaborate closely with frontend engineers, product managers, and site reliability engineers to ensure that our services meet the high availability requirements of our users.

Beyond coding, you will play a key role in the technical evolution of our platform. This includes identifying opportunities to reduce technical debt, improving system performance, and mentoring other engineers. You will often work on cross-team initiatives, requiring you to communicate complex technical concepts to stakeholders across the organization.

A strong candidate for this role possesses a deep technical background and a pragmatic approach to software development. We look for engineers who are not only proficient in their language of choice but also understand the broader ecosystem in which their code operates.

• Must-have skills: Proficient in backend development, hands-on experience with Docker, strong understanding of API design principles, and experience working in an agile, cross-functional team.
• Nice-to-have skills: Experience with cloud infrastructure (e.g., AWS), knowledge of healthcare data standards, and experience with distributed systems.
• Experience: We look for engineers who have demonstrated growth and impact in their previous roles, typically showing a history of owning features or services from conception to launch.

Q: How long should I spend preparing for the technical rounds? A: Dedicate enough time to be comfortable with your core language and system design patterns. Quality of preparation—focusing on articulating your reasoning—is more important than the quantity of hours spent.

Q: What is the most important trait you look for? A: We value "technical humility" and a "growth mindset." We want engineers who can admit when they don't know something but are eager to learn and solve the problem.

Q: How does the team handle remote work? A: Included Health is a distributed-friendly organization. We rely on strong documentation and clear communication to keep our teams aligned regardless of physical location.

• Prioritize clarity: When solving a coding problem, speak your thoughts aloud. The interviewer is interested in how you navigate dead ends as much as how you reach the solution.
• Know your stack: Be ready to explain the "why" behind the technologies you have used in past projects. Don't just list tools; explain why they were the right fit for the problem.
• Focus on the "why": Whether discussing a past project or a system design challenge, always ground your decisions in the business or technical requirements of the situation.
• Prepare questions: At the end of every round, you will have time to ask questions. Use this to show your interest in our mission and your desire to understand how the team operates.

Becoming a Backend Engineer at Included Health is an opportunity to solve some of the most pressing challenges in the healthcare industry. By focusing on your technical fundamentals, demonstrating a collaborative spirit, and clearly communicating your problem-solving process, you will be well-positioned to succeed in our interview process.
