Highmark Health Software Engineer interview questions & guide 2026

The interview questions at Highmark Health are designed to evaluate both your foundational engineering knowledge and your behavioral alignment with the company’s collaborative culture. Questions are drawn from real interview experiences and are structured to test patterns of thinking rather than rote memorization. Expect a strong mix of verbal technical concepts and structured behavioral inquiries.

Object-Oriented Programming & Java

Because a significant portion of Highmark Health's tech stack is built on enterprise Java, interviewers place a heavy emphasis on core object-oriented programming (OOP) principles.

• Explain the four pillars of Object-Oriented Programming (OOP) and how you have applied them in a recent project.
• What is the difference between an abstract class and an interface in Java? When would you use one over the other?

Preparing for an interview at Highmark Health requires a balanced approach. While you must be technically sound, your interpersonal skills, communication style, and alignment with the company's mission are heavily weighted.

To succeed, you should focus your preparation on four key evaluation criteria:

Role-Related Knowledge – You must demonstrate a strong grasp of software engineering fundamentals. This means being able to verbally explain Java, OOP concepts, and database design. You will not face intense, high-pressure whiteboarding algorithms, but you must be able to discuss code architecture and system integration clearly.

STAR-Method Behavioral Delivery – Because behavioral questions make up a significant portion of the final round, you must prepare structured stories. Practice explaining past situations, the specific tasks you were charged with, the actions you took, and the quantifiable results of your efforts.

Adaptability & Support Orientation – Healthcare systems require continuous uptime. Interviewers will evaluate your willingness to participate in alternate work schedules, on-call rotations, and your enthusiasm for learning new enterprise tools like Pega or cloud technologies.

Culture & Mission Alignment – Highmark Health is a mission-driven organization focused on improving health experiences. Be ready to explain why you want to work in healthcare and how you maintain a patient-first mindset, even when writing back-end code.

The interview process for a Software Engineer at Highmark Health is straightforward, conversational, and highly focused on team fit. Candidates typically experience a structured journey that progresses from initial screening to a comprehensive team panel.

Historically, the process consists of three main stages:

First, you will complete a phone screen with a recruiter to discuss your resume, background, location preferences, and basic skills alignment. Second, you will have a video or phone interview with the hiring manager. This round dives deeper into your technical experience, project history, and domain knowledge.

The final stage is a team interview, which is frequently conducted as a panel. This panel typically consists of five to six people, including tech leads, senior engineers, and managers. This round is highly structured, with roughly 20% of the time focused on technical fundamentals, 20% on domain/project skills, and 60% on behavioral questions using the STAR technique. The atmosphere is designed to be welcoming, and you will have ample opportunity to ask questions at the end.

The visual timeline above outlines the standard progression from your initial application to the final team panel. Candidates should use this timeline to pace their preparation, ensuring they master foundational technical concepts before moving on to intensive behavioral prep for the final round. While the overall process is highly structured, the exact timeline can vary depending on the specific team, location, and business needs.

To stand out during the Highmark Health interview process, you must excel in three core evaluation areas. Understanding what strong performance looks like in each area will help you tailor your preparation.

Object-Oriented Programming (OOP) & Core Java

Highmark Health relies heavily on enterprise Java for its backend systems. Interviewers will verbally test your understanding of software design principles to ensure you can write clean, maintainable, and scalable code.

Be ready to go over:

• Four Pillars of OOP – Deep conceptual understanding of encapsulation, inheritance, polymorphism, and abstraction.
• Java Fundamentals – Memory management, garbage collection, collections framework (Lists, Sets, Maps), and exception handling.
• Design Patterns – Familiarity with common patterns like Singleton, Factory, and Observer, and when to apply them.
• Advanced concepts (less common) – Multithreading, concurrency utilities, and Java memory model optimization.

Example questions or scenarios:

• "Can you explain how polymorphism allows us to write more flexible and reusable code, and provide a real-world example from your past work?"
• "What is the difference between a HashMap and a TreeMap in Java, and how do their time complexities differ?"
• "How would you handle thread safety in a multi-threaded Java application?"

Data Management & Databases

Healthcare applications require robust, secure, and highly optimized data transactions. You must demonstrate that you can interact with relational databases efficiently and design schemas that protect data integrity.

Be ready to go over:

• SQL Queries & Joins – Writing and explaining complex queries, including inner, outer, left, and right joins.
• Database Optimization – Using indexes, analyzing execution plans, and normalizing tables to eliminate redundancy.
• Data Integrity & Security – Understanding constraints, transactions, and basic data security practices.
• Advanced concepts (less common) – NoSQL databases, database partitioning, and ETL (Extract, Transform, Load) processes.

Example questions or scenarios:

• "How would you design a relational database schema for an insurance claims system where a single member can have multiple claims?"
• "If a report that queries database records is running incredibly slowly, what steps would you take to diagnose and resolve the performance bottleneck?"
• "What are ACID properties in database transactions, and why are they critical in a healthcare environment?"

Behavioral Competency (STAR Method)

Because the final round is heavily weighted toward behavioral evaluation (up to 60%), your ability to articulate your soft skills is just as important as your technical ability. Interviewers use standard question packets to evaluate how you handle team dynamics, conflict, and pressure.

Be ready to go over:

• Collaboration & Conflict – Resolving disagreements with peers, working in cross-functional teams, and supporting colleagues.
• Adaptability – Learning new tools (like Pega), pivoting when project requirements change, and handling ambiguous tasks.
• Problem-Solving under Pressure – Managing production outages, tight deadlines, and competing priorities.
• Advanced concepts (less common) – Mentoring junior engineers, influencing technical decisions without authority, and advocating for process improvements.

Example questions or scenarios:

• "Tell me about a time you had to work on a project with vague or incomplete requirements. How did you proceed?"
• "Describe a situation where you made a mistake on a project. How did you identify it, what did you do to correct it, and what did you learn?"
• "Give me an example of a time when you had to balance a heavy workload with a sudden, urgent support request. How did you manage your time?"
