🚨 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.

How much fail safe period do Transient tables have in Snowflake?
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! 🎉

🚀 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!

You need to combine two lists of customer IDs from two different tables. You want the fastest performance possible and you don't mind if some IDs appear twice. Which operator do you use?

UNION

EXCEPT

UNION ALL

EXCEPT
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.📈
FAANG SQL Challenge: Can you solve "The Delimiter Trap"? 🧩

I just dropped a new breakdown of a classic interview problem that trips up even Senior Data Engineers.

The Task: Extract and calculate reward points from a single "messy" column (e.g., `'MM:CI:CD'`).

Why you should watch:
✅ Learn the cleanest way to use STRING_SPLIT.
✅ Master Conditional Aggregation (no more spaghetti code!).
✅ Avoid the #1 over-engineering mistake candidates make in FAANG interviews.

Stop struggling with messy data—master the logic in 5 minutes.

Watch the full solution here:
👇👇👇

Which one is faster for this—`STRING_SPLIT` or CROSS APPLY? Let me know in the YouTube comments! 🚀

Career growth rarely comes from one big move.
It comes from showing up every day — even when no one is watching.

• Learn when it’s boring
• Practice when progress feels slow
• Stay consistent when results aren’t visible

Perseverance compounds quietly.

If you can stay disciplined for long enough,
your career will look very different by the end of 2026.

No hacks.
No shortcuts.
Just consistency.🔥

Hey Data Engineers

One individual from this community just had an Snowflake DBT interview with TCS,these are the main questions asked into him

Snowflake + dbt interview questions asked at TCS 👇

These are not beginner-level questions — they test real production understanding.

• Difference between Snowpipe vs COPY INTO
• Can you clone a subset of a table in Snowflake?
• Track column value changes (Apple → Orange) using Streams + MERGE
• Types of views in Snowflake and their use cases
• What is CLUSTER BY and how many columns should be used?

• Is a Stream a database object in Snowflake?
•How do you register a source in dbt?
• Difference between external table and managed tables in snowflake?

If you can confidently answer these,
you’re already ahead of most candidates.

More Snowflake & dbt interview content coming soon 🚀

🧠 Amazon SQL Interview Challenge
This is an interesting challenge ,please take a look

Ever tried applying Pythagoras theorem in SQL? 😄

You’re given triangle sides stored row-wise and your task is to identify which CombinationID forms a right-angled triangle.

📐 Rule to apply:
H² = P² + B² (longest side matters!)



If this showed up in an interview, how would you approach it?
