About the role

Zelis is a global healthcare technology and financial solutions firm that helps payers, providers, and consumers in the United States achieve greater transparency and efficiency in claims processing and payments. The company’s platform leverages modern cloud, AI, and data‑driven services to simplify complex financial workflows. In India, Zelis operates a technology hub that supports product development, data engineering, and infrastructure initiatives, offering fresh talent exposure to a fast‑growing, mission‑critical domain. The work culture emphasizes collaboration across geographies, continuous learning, and the chance to contribute to solutions that impact real‑world healthcare finance. The Intern / Associate Software Engineer – Technology role is designed for students and recent graduates who want to start a career in technology without prior professional experience. Candidates will be evaluated on programming fundamentals, analytical thinking, and a willingness to learn. Depending on assessment outcomes and business needs, successful applicants may be placed in one of several technology streams such as Software Engineering, Data Engineering, Cloud & DevOps, Quality Engineering, AI/ML, Cybersecurity, Infrastructure, or Business Systems. The role offers a hybrid work model, allowing a blend of on‑site collaboration and remote productivity. Key responsibilities include: 1. Assist senior engineers in designing, coding, and testing software components across assigned streams. 2. Participate in requirement gathering sessions and translate business needs into technical specifications. 3. Develop and maintain simple APIs, scripts, or data pipelines as per project requirements. 4. Perform unit testing, debug issues, and document findings in a clear manner. 5. Contribute to code reviews and adopt best practices for version control and CI/CD. 6. Support data ingestion, transformation, or reporting tasks for analytics projects. 7. Help automate deployment processes or infrastructure provisioning using cloud tools. 8. Execute test cases, log defects, and assist in building automated test suites. 9. Explore AI/ML models or security testing frameworks when aligned with the stream. 10. Collaborate in Agile ceremonies, share progress, and continuously seek feedback. Typical tech stack exposure may include Java or Python for application development, SQL/NoSQL databases, AWS or Azure cloud services, Docker/Kubernetes for containerization, Git for source control, and testing frameworks like JUnit or Selenium. For AI/ML streams, candidates might work with TensorFlow, PyTorch, or scikit‑learn. The program is structured to provide mentorship, regular learning sessions, and a clear growth path from intern to full‑time associate, with opportunities to specialize further or rotate across streams based on performance. Why join Zelis? The company offers a chance to work on high‑impact healthcare finance solutions, access to global experts, and a supportive environment that values curiosity and innovation. Freshers gain hands‑on experience with cutting‑edge technologies, a clear roadmap for career progression, and the flexibility of a hybrid work model that balances learning with real‑world delivery.

Technical questions 5
What is the difference between WHERE and HAVING clauses in SQL? Answer
Model answer: WHERE filters rows before any groupings are applied, while HAVING filters aggregated groups after GROUP BY has executed.
Explain SQL Window functions: ROW_NUMBER(), RANK(), and DENSE_RANK(). Answer
Model answer: ROW_NUMBER() assigns unique sequential integers. RANK() assigns identical ranks to ties and skips ranks. DENSE_RANK() assigns identical ranks to ties without skipping rank numbers.
How do you handle NULL and missing values during data cleaning in Python/Pandas? Answer
Model answer: Use .isna().sum() to identify missing values. Impute with mean/median using .fillna() or remove with .dropna(subset=[...]) depending on variance impact.
What is the difference between Star Schema and Snowflake Schema in Data Warehousing? Answer
Model answer: Star Schema has denormalized dimension tables directly connected to the central Fact table. Snowflake Schema normalizes dimension tables into sub-dimensions to minimize redundancy.
How do you calculate MoM (Month-over-Month) growth in SQL? Answer
Model answer: Use LAG(revenue, 1) OVER (ORDER BY month) to fetch the previous month's revenue and compute (revenue - prev_revenue) / prev_revenue * 100.
Behavioural & HR questions 3
