Example scenarios:

• "Design a real-time notification system that alerts members when their insurance claim status changes."
• "Architect a system to ingest, normalize, and store electronic health records (EHR) from thousands of clinics."

Product Demo & Case Study

This unique round evaluates your product sense and ability to think cross-functionally. You will often walk through a demo of the Oscar Health app or discuss a case study involving a real-world business challenge.

Be ready to go over:

• Stakeholder Analysis – Identifying how a technical issue impacts members, providers, and internal operations.
• Prioritization – Deciding which features or bug fixes to prioritize based on business value and user impact.
• System Integration – Explaining how frontend applications interface with complex backend insurance engines.

Example scenarios:

• "Analyze a proposed feature for the member app that allows users to estimate their out-of-pocket costs before a doctor's visit. What are the technical and operational challenges?"
• "A bug is preventing providers from submitting claims online. Walk through your immediate triage steps and long-term architectural solutions."

As a Software Engineer at Oscar Health, you will be responsible for the end-to-end delivery of high-impact technical solutions. Your day-to-day work will involve:

• Designing and building scalable software – Writing clean, maintainable, and well-tested code in languages like Python, Go, Java, or TypeScript.
• Collaborating cross-functionally – Working closely with product managers, data scientists, and operational teams to define requirements and deliver user-centric features.
• Maintaining system reliability – Monitoring production systems, debugging complex issues, and continuously improving code quality and system performance.
• Contributing to engineering excellence – Participating in code reviews, mentoring junior engineers, and helping to shape the team's technical roadmap.

Oscar Health seeks talented engineers who can thrive in a fast-paced, collaborative environment. The ideal candidate meets the following criteria:

• Must-have skills – Strong proficiency in at least one modern programming language (e.g., Python, Java, Go, JavaScript/TypeScript). Solid understanding of data structures, algorithms, and object-oriented design. Experience with relational databases and SQL.
• Nice-to-have skills – Experience with cloud platforms (AWS, GCP), containerization (Docker, Kubernetes), and modern frontend frameworks (React). Familiarity with healthcare data standards (HIPAA, FHIR) is a strong plus but not required.
• Experience level – Typically 2+ years of professional software engineering experience for mid-level roles, and 5+ years for senior-level positions.
• Soft skills – Excellent communication skills, a proactive attitude, and a strong desire to solve complex, mission-driven problems.

Q: How technical are the recruiter and HR screens? A: The initial screen is non-technical and focuses on your background, career goals, and alignment with the company's mission. However, you should be ready to speak high-level about your past projects and technical choices.

Q: What programming languages can I use in the coding interviews? A: You can generally use any language of your choice (such as Python, Java, Go, or JavaScript) for the coding rounds. It is highly recommended to choose the language you are most comfortable with and understand its built-in libraries thoroughly.

Q: How does the virtual onsite differ for frontend vs. backend roles? A: Frontend candidates will face questions focused on UI architecture, JavaScript/TypeScript, and state management, while backend candidates will be evaluated heavily on distributed systems, databases, and API design. Ensure your recruiter clarifies your track before the onsite.

Q: How long does it take to hear back after the final round? A: While timelines can vary, candidates typically receive feedback within one to two weeks following the virtual onsite. The hiring committee reviews all signals before a final offer decision is made.

• Over-communicate your thought process: During coding and system design rounds, talk through your ideas before writing any code. This allows the interviewer to understand your methodology and offer guidance if you start heading down an incorrect path.
• Be adaptive to feedback: If an interviewer suggests a different approach, do not dogmatically defend your initial solution. Oscar Health values collaborative engineers who can take constructive feedback and pivot when necessary.
• Understand the business model: Spend time researching how health insurance works, including concepts like premiums, deductibles, copays, and claims processing. Having this domain context will help you stand out in product and behavioral rounds.

• Prepare detailed project examples: For behavioral rounds, have three to four detailed stories prepared using the STAR method (Situation, Task, Action, Result). Focus on projects where you navigated ambiguity, solved a complex technical bug, or collaborated across teams.

Preparing for a Software Engineer role at Oscar Health requires a balanced approach. You must sharpen your algorithmic coding skills, master distributed system design principles, and cultivate a deep understanding of product empathy. By focusing on these core areas, you can walk into your interviews with confidence.
