In this video, Iโ€™ll walk you through my entire step-by-step solution in SQL Server, breaking down the logic clearly so you can learn, understand, and apply it in your own interviews ๐Ÿ’ผ

Hello Data Engineers, one of my mentees interview experience for 4 years of experience

The candidate was offered 15LPA

๐Ÿš€ Snowflake Interview Experience โ€” LTIMindtree (Shortlisted)

Sharing the questions they asked and quick answers so you can prepare better ๐Ÿ‘‡

1. How to ingest data from on-prem SQL DB to Snowflake?
Answer: Extract data using ADF/Python, land it in Blob/S3, create a stage, and load using COPY INTO. Simple flow: On-prem DB โ†’ Staging โ†’ Snowflake Stage โ†’ Table.

2. What is incremental load in Snowflake?
Answer: Load only new or changed rows using last_updated column, CDC, or MERGE command. Helps avoid full reloads.

3. Materialized Views โ€“ what and when?
Answer: Precomputed query results stored physically. Useful when the same heavy query is run often and data doesnโ€™t change very fast.

4. How to move data from Azure Blob to Snowflake?
Answer: Create an external stage pointing to Blob and load data using COPY INTO. Stages act like temporary parking space for files.

These are only partial answers that I have added
Thanks

๐Ÿš€ How to Become a Better Data Engineer

You donโ€™t become a better Data Engineer by memorizing tools. You grow by thinking like one.
Start doing this daily:
๐Ÿ”น Understand why data flows the way it does ๐Ÿ”น Break problems into clean, logical steps ๐Ÿ”น Write SQL thatโ€™s simple, not โ€œsmartโ€ ๐Ÿ”น Learn one new thing every day โ€” even 10 minutes counts ๐Ÿ”น Build small projects that feel real, not theoretical ๐Ÿ”น Read other peopleโ€™s code (it teaches more than tutorials)
Consistency beats complexity. And the engineers who win arenโ€™t the ones who know the most tools โ€” theyโ€™re the ones who know how to solve problems calmly and clearly.
Keep going. Youโ€™re closer than you think ๐Ÿ’ช
