About the role

Cognizant, a global leader in digital, technology and consulting services, has built a reputation for delivering end‑to‑end solutions across industries. With a workforce of over 300,000 professionals, the company blends deep domain expertise with cutting‑edge technologies such as AI, cloud, and analytics to help enterprises transform. Cognizant’s culture emphasizes continuous learning, collaboration, and a strong focus on quality, making it an attractive destination for fresh talent looking to start a career in a fast‑paced environment. The role is posted on Naukri.com, India’s premier job portal, which connects millions of job seekers with top employers and offers a seamless application experience. The Mapping Role (Data) is designed for fresh graduates who are enthusiastic about geography, map navigation, and data accuracy. As a Mapping Analyst, you will be responsible for analysing, validating, and maintaining large volumes of location‑based data, ensuring that the information fed into Cognizant’s AI‑driven platforms is precise and reliable. You will work in a 24/7 rotational shift from the Hyderabad office, collaborating with cross‑functional teams to support various client projects that rely on geospatial intelligence. Key responsibilities include: 1. Collecting and ingesting raw mapping data from multiple sources. 2. Validating data for correctness, completeness, and consistency. 3. Updating and maintaining GIS databases and related metadata. 4. Conducting quality checks and generating audit reports. 5. Collaborating with senior analysts to resolve data discrepancies. 6. Using GIS tools (e.g., ArcGIS, QGIS) and Excel for data manipulation. 7. Documenting standard operating procedures for mapping workflows. 8. Identifying opportunities for process automation and improvement. 9. Providing timely support to internal stakeholders during critical project phases. 10. Adhering to data security and confidentiality guidelines. Technical stack primarily involves GIS software, basic SQL, Excel, and scripting basics for data cleaning. The growth path typically moves from Mapping Analyst to Senior Analyst, then to Team Lead or Project Manager, with ample learning opportunities through Cognizant’s internal training platforms. Joining this role offers exposure to real‑world geospatial projects, a chance to develop analytical rigor, and a clear trajectory within a globally recognized organization. Why join? Cognizant’s commitment to innovation, its robust mentorship programs, and the opportunity to work on high‑impact projects make it an ideal launchpad for freshers. The rotational shift model also ensures you gain experience across different time zones and client requirements, building a versatile skill set early in your career.

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
