Top 25 Azure Data Engineering Training in Chennai Interview Questions and Answers (2026)
These are the questions Chennai hiring managers are asking right now in interviews for Data Engineering roles. Practise them out loud before every interview — the answers below are what experienced interviewers expect to hear.
Q1. What is Azure Data Factory?
Azure Data Factory (ADF) is a cloud-based ETL and data integration service. It allows you to compose data-driven workflows (pipelines) that ingest, transform, and load data from 90+ sources into Azure data stores.
Q2. What is the difference between Azure Data Factory and Synapse Pipelines?
Synapse Pipelines is essentially ADF embedded inside Synapse Analytics. It uses the same drag-and-drop authoring and 90+ connectors. The advantage of Synapse is the tight integration with serverless SQL pools and dedicated SQL pools.
Q3. What is Microsoft Fabric?
Microsoft Fabric is a unified analytics platform that brings together Synapse, Data Factory, Power BI, and OneLake into a single SaaS experience. It uses Delta Lake and OneLake as the data foundation.
Q4. Explain the medallion architecture.
The medallion architecture is a data design pattern with three layers: Bronze (raw, append-only, source data), Silver (cleaned, deduplicated, conformed), and Gold (curated, business-level, aggregated). It is widely used in Databricks and Microsoft Fabric.
Q5. What is Delta Lake?
Delta Lake is an open-source storage layer that brings ACID transactions, schema enforcement, time travel, and unified batch + streaming to Apache Spark. It is the default storage format in Databricks and Microsoft Fabric.
Q6. What is the difference between batch and stream processing?
Batch processing handles data in large, scheduled chunks (every hour, every night). Stream processing handles data event-by-event in near real time (sub-second to sub-minute latency). Streaming is needed for fraud detection, IoT, and clickstream analytics.
Q7. How do you handle slowly changing dimensions (SCD) in ADF?
Use a Mapping Data Flow with a SCD transformation. Choose Type 1 (overwrite), Type 2 (historical, with effective dates and surrogate key), or Type 3 (limited history in additional columns). Databricks Delta Lake offers MERGE INTO for SCD Type 2 in code.
Q8. What is Azure Data Lake Storage Gen2?
ADLS Gen2 is a hierarchical file system built on top of Azure Blob Storage, optimized for big-data workloads. It provides low-cost tiered storage, POSIX-compliant ACLs, and is the data lake foundation for ADF, Synapse, and Databricks.
Q9. What is the difference between serverless SQL pool and dedicated SQL pool in Synapse?
Serverless SQL pool is pay-per-query (by data processed) and is used for ad-hoc exploration and reporting on files in ADLS. Dedicated SQL pool (formerly SQL DW) is a provisioned MPP database for enterprise data warehousing with predictable performance.
Q10. What is a Spark cluster in Azure Databricks?
A Spark cluster is a set of compute nodes that run the Spark engine. Databricks supports all-purpose clusters (interactive) and job clusters (ephemeral, for production jobs). Choose instance types based on workload: memory-optimized for joins, compute-optimized for ETL, GPU for ML.
Q11. What is Unity Catalog in Databricks?
Unity Catalog is Databricks’ unified governance solution. It provides a single place to manage data assets, permissions, lineage, and audit across workspaces. It enforces fine-grained access control at the table, column, and row level.
Q12. How do you secure secrets in Azure Data Factory?
Use Azure Key Vault to store secrets and link them to ADF via a Key Vault connection. Reference the secret inside a Web activity or as a connection password. Never hardcode secrets in linked services or pipelines.
Q13. What is a tumbling window trigger in ADF?
A tumbling window trigger runs a pipeline on a fixed time window (e.g. hourly, daily) for a contiguous series of windows. It is the recommended pattern for reliable backfill and rerun of failed windows.
Q14. How do you implement incremental loading in ADF?
Use a watermark column (e.g. LastModifiedDate) or a change-data-capture flag. The pipeline reads the high-water mark from a control table, filters source rows greater than the watermark, loads the delta, and updates the watermark. ADF also supports Change Data Capture (CDC) in Mapping Data Flows.
Q15. What is the difference between a pipeline and a data flow in ADF?
A pipeline orchestrates activities (Copy, Databricks, Web, Stored Procedure) and is free of charge. A data flow is a visual Spark engine that runs transformations on a Spark cluster and is billed per vCore-hour. Use pipelines for orchestration; use data flows for visual transformations.
Q16. What is the difference between partitioning and bucketing in Spark?
Partitioning splits data into directories by a column value (e.g. year=2026/month=08/day=18). Bucketing distributes data into a fixed number of files by a hash of a column. Partitioning speeds up filtering; bucketing speeds up joins on the bucketed column.
Q17. How do you handle late-arriving data in streaming pipelines?
Use windowed aggregation with a watermark (allowed lateness) in Structured Streaming. For very late data, write to a quarantine Delta table and reconcile in a separate batch job. The choice depends on the business SLAs for the late data.
Q18. What is a star schema vs a snowflake schema?
In a star schema, a central fact table joins directly to denormalized dimension tables. In a snowflake schema, dimensions are normalized into multiple related tables. Star is simpler and faster for queries; snowflake saves storage and is more normalized.
Q19. How do you choose between ADF and Databricks for a transformation?
Use ADF for orchestration, simple transformations, copy activity, and integration with the rest of Azure. Use Databricks for complex transformations, Python/Scala code, ML, and large-scale Spark jobs. Most production architectures use ADF for orchestration and Databricks for transformation.
Q20. What is a data lakehouse?
A data lakehouse is a hybrid architecture that combines the low-cost storage and flexibility of a data lake with the ACID transactions, schema enforcement, and query performance of a data warehouse. Delta Lake, Apache Iceberg, and Apache Hudi are the leading open table formats.
Q21. How do you monitor data pipeline failures?
Use Azure Monitor + Log Analytics to capture ADF activity runs, Spark logs, and Databricks job runs. Set up alerts on failure rates, durations, and data quality checks. Build a dashboard that surfaces failed activities, retry counts, and SLA breaches.
Q22. What is the role of Purview in Azure data engineering?
Microsoft Purview is the unified data governance solution. It catalogs data assets across ADF, Synapse, Databricks, and Power BI, enforces access policies, and tracks data lineage. Use Purview to discover sensitive data and meet compliance requirements.
Q23. How do you test data pipelines?
Use a layered testing strategy: unit tests on transformation logic (pytest + chispa for Spark), integration tests on the pipeline (Assert activity in ADF), data quality tests (Great Expectations, Soda, dbt tests), and end-to-end tests on business KPIs.
Q24. What is the difference between ETL and ELT?
ETL transforms data before loading into the destination (typical for traditional data warehouses). ELT loads raw data first and transforms inside the destination (typical for cloud data warehouses and lakehouses with cheap compute). Modern architectures favor ELT.
Q25. How do you estimate cost for an Azure data engineering solution?
Cost components: ADF (per activity run and per Data Flow vCore-hour), Synapse SQL pool (per DWU-hour, paused when idle), Databricks (per DBU-hour), storage (per GB-month). Use the Azure Pricing Calculator and add buffer for development, testing, and DR.
