Athenahealth's Interview Process (2026)

Athenahealth Interview Process
The Athenahealth software engineer interview process typically spans 4 to 6 stages and places a strong emphasis on clean, optimized code alongside domain-aware thinking. The experience can vary by team and role, but most candidates report a consistent structure that moves from an automated assessment through technical rounds and into design and behavioral discussions.
  • Recruiter Screen: An initial call, usually around 15 to 30 minutes, covering your resume, motivation, and the specific team you are being considered for, such as Platform, Revenue Cycle Management, or Clinicals.
  • Online Assessment: A timed HackerRank assessment, typically around 90 minutes, that generally includes 2 to 3 DSA coding problems, a SQL query, and multiple-choice questions on CS fundamentals like operating systems, networking, and databases.
  • Technical Interview I: A live coding round, usually 60 to 75 minutes, focused on core language proficiency (often Java or C++) and DSA, with interviewers also probing deeper concepts like multithreading and ORM internals.
  • Technical Interview II / Onsite: A longer set of rounds, often described as a Super Day format lasting 2 to 4 hours, that typically covers Low-Level Design, High-Level Design, and more advanced coding challenges using whiteboard or digital diagramming tools.
  • Managerial / Hiring Manager Round: A conversation, usually around 45 to 60 minutes, focused on your past project architecture decisions, how you handle technical disagreements, and how well you understand the business impact of your work.
  • HR Round: A final discussion, typically around 30 minutes, covering compensation expectations, benefits, and company culture.
To prepare effectively for Athenahealth's interview, focus your study plan across these key areas:
  • Data Structures & Algorithms (DSA): LeetCode-style coding problems ranging from medium to hard difficulty, often presented in healthcare-flavored contexts.
  • SQL: Complex SQL queries and schema design problems that appear in both the online assessment and the design rounds.
  • High-Level Design: System design problems focused on scalable architectures, often tied to healthcare-specific scenarios like notification systems or billing platforms.
  • Low-Level Design: Object-oriented design problems requiring you to define data entities, relationships, and class structures, sometimes alongside SQL schema design.
  • CS Fundamentals: Multiple-choice and discussion questions on operating systems, networking, databases, and language internals like multithreading and ORM behavior.
  • Behavioral: Situation-based questions exploring how you handle technical disagreements, legacy system optimization, and team collaboration.
1. Data Structures & Algorithms (DSA)Athenahealth's DSA bar is high, and candidates in 2025 and 2026 consistently report that reaching the optimal time complexity is a hard requirement, not just a nice-to-have. If your solution works but runs in suboptimal time, interviewers have been known to reject it regardless of how well you communicated your reasoning.Recent candidates have reported seeing problems like Largest Rectangle in Histogram, Sort Colors, and interval-based problems similar to Meeting Rooms II. Athenahealth often wraps these in healthcare contexts, so a sorting problem might be framed as prioritizing patient records by triage logic rather than sorting an array.For the online assessment, practice intervals, sorting algorithms, and stacks in particular. A good starting point for broader preparation is our top 100 DSA questions, which covers the most commonly tested problem types across all difficulty levels.
2. SQLSQL is tested more seriously at Athenahealth than most candidates expect. The online assessment includes at least one SQL query problem, and the design rounds may require you to write complex joins on the spot as part of a schema design exercise. Get familiar with these types of questions by practicing our SQL coding examples. Practice writing multi-table joins, aggregate queries, and nested subqueries. Candidates have been asked to design billing schemas that handle insurance claims and charges, and then immediately write queries against that schema, so fluency in both design and syntax matters. Brush up on SQL theory to make sure you are solid on joins, indexing, and query optimization before your assessment.
3. High-Level DesignThe onsite or virtual Super Day typically includes at least one High-Level Design round. Candidates report being asked to design systems like a notification system for patient alerts or a healthcare claims processing platform, so familiarity with healthcare-specific data flows is an asset.You are expected to define components, discuss trade-offs, and handle scale. For interactive practice drawing out architectures, try our System Design practice tool to get comfortable with the whiteboard format used in these rounds.For a solid conceptual foundation, review core design concepts including load balancing, message queues, and database sharding, all of which tend to come up in healthcare-scale system discussions.
4. Low-Level DesignThe LLD round at Athenahealth typically asks you to model a real-world system using classes, interfaces, and relationships. You can expect to define entity relationships (one-to-one, one-to-many, many-to-many) and sometimes write the SQL schema to match your design.Problems like Thread-Safe Singleton and Design BigInteger reflect the kind of object-oriented thinking and concurrency awareness that interviewers look for. Low-Level Design practice is a good place to build the muscle memory for modeling systems under time pressure.
5. CS FundamentalsThe online assessment includes multiple-choice questions on operating systems, networking, and database concepts, so these are not areas to skip. Candidates have been specifically asked about how HashMaps work internally, multithreading and race conditions, and ORM issues like the N+1 query problem.For backend roles, interviewers in the Technical Interview I round often probe Spring Boot internals including bean lifecycle, annotation behavior, and transaction isolation levels. Review operating systems concepts and networking fundamentals to shore up the theory side before your assessment.
6. BehavioralThe managerial round at Athenahealth focuses on how you have handled real situations, particularly around technical decision-making and working with legacy systems. Common questions include how you respond when your technical approach differs from your manager's, and how you have approached optimizing a system that was not originally yours.Structure your answers using the STAR principle to keep your responses focused and concrete. It also helps to show some familiarity with healthcare concepts like Revenue Cycle Management or Electronic Health Records, as interviewers respond well to candidates who connect their technical decisions to real business impact. The Behavioral Playbook is a useful resource for preparing stories that feel specific and genuine rather than rehearsed.
ConclusionAthenahealth rewards candidates who combine strong technical fundamentals with an understanding of how their code serves the healthcare domain. Start with DSA and SQL, layer in system design practice, and make sure your behavioral stories are grounded in real trade-offs you have navigated. For a structured path through every stage of the process, follow the Athenahealth Interview Roadmap to build your preparation plan and move into interviews with confidence.
