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

The candidate was offered 15LPA

🚀 Snowflake Interview Experience — LTIMindtree (Shortlisted)

Sharing the questions they asked and quick answers so you can prepare better 👇

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 → Staging → Snowflake Stage → 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 – what and when?
Answer: Precomputed query results stored physically. Useful when the same heavy query is run often and data doesn’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

😲 99% of SQL learners struggle with this problem!
You get a Club table where each member earns rewards like:
MM, CI, CO (0.5 pts each) CD, CL, CM (1 pt each)

💥 Challenge: Calculate the total points scored by each club using SQL. Sounds simple? Wait till you try it. 😏
Most people miss the key logic 👀
Can you crack it before watching the solution?

🚀 How to Become a Better Data Engineer

You don’t become a better Data Engineer by memorizing tools. You grow by thinking like one.
Start doing this daily:
🔹 Understand why data flows the way it does 🔹 Break problems into clean, logical steps 🔹 Write SQL that’s simple, not “smart” 🔹 Learn one new thing every day — even 10 minutes counts 🔹 Build small projects that feel real, not theoretical 🔹 Read other people’s code (it teaches more than tutorials)
Consistency beats complexity. And the engineers who win aren’t the ones who know the most tools — they’re the ones who know how to solve problems calmly and clearly.
Keep going. You’re closer than you think 💪

🚨 Paytm Data Engineer Interview Pattern (4+ YOE | ~20 LPA)

If you’re preparing for a mid–senior Data Engineer role, Paytm keeps testing the same core patterns again and again.

They focus heavily on: • Advanced SQL (window functions, latest record logic) • Spark & PySpark performance • Data skew & slow job debugging • Idempotent and incremental pipelines • Real-world data quality & schema drift problems
These aren’t trick questions — they test how you think in production scenarios.
🔁 Share it with someone preparing for DE interviews 💪 Prep smart, not random

Transient table do not have any fail safe period in Snowflake for cost effective ness ,they are used to store less critical data that does not require data backup from
Fail safe point of view

So the correct answer is Option C

🎉 Happy New Year, SQL Family! 🎉
As we wrapped up 2025, I just want to say thank you 🙏
From learning SQL basics to discussing real interview and production scenarios — this journey has been amazing because of you.

Your reads, reactions, and discussions make this channel what it is 💙

In 2026, expect:
🚀 More SQL interview questions
🧠 Deeper data engineering concepts
⚙️ Practical, real-world patterns
Let’s keep learning, sharing, and growing together.
Wishing you all a year full of growth and success! ✨

🚀 SQL SET Operators: The Quick Guide 🚀
Stop trying to solve everything with JOINs! If you need to combine data vertically, these are your best friends:
🔹 UNION Combines results and removes duplicates. Perfect for a clean, unique list. 🧹
🔹 UNION ALL Combines everything, including duplicates. It's much faster because the DB doesn't have to scan for duplicates! ⚡️
🔹 INTERSECT Finds the common ground. Only returns rows that exist in both datasets. 🤝
🔹 EXCEPT / MINUS The "difference" finder. Shows what's in your first query but NOT in the second. 🚫

💡 Pro-Tip for Interviews: Always remember: For SET operators to work, your queries must have the same number of columns and matching data types!

#SQL #DataScience #Database #CodingTips #DataAnalytics #InterviewPrep #TechSkills #SQLServer

The correct answer is Union all
This is a really common interview question just to check basics
Union all is faster that union because it does not sort or deduplicate data.📈
