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

Stop struggling with messy dataβ€”master the logic in 5 minutes.

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 πŸ‘‡

These are not beginner-level questions β€” they test real production understanding.

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

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

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

Ever tried applying Pythagoras theorem in SQL? πŸ˜„

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

πŸ“ Rule to apply:
HΒ² = PΒ² + BΒ² (longest side matters!)



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

πŸš€ Essential SQL Commands Every Data Professional Should Know

Whether you’re preparing for SQL interviews or working with databases daily, these commands form the backbone of SQL.

Here’s a quick refresher πŸ‘‡

πŸ”Ή SELECT – Retrieve data from a table
πŸ”Ή INSERT – Add new records into a table
πŸ”Ή UPDATE – Modify existing data
πŸ”Ή DELETE – Remove specific records

πŸ“¦ Database Structure

πŸ”Ή CREATE – Create new database objects (tables, databases)
πŸ”Ή ALTER – Modify the structure of an existing object
πŸ”Ή DROP – Delete an entire table or database

πŸ“Š Filtering & Analysis

πŸ”Ή WHERE – Filter records based on conditions
πŸ”Ή GROUP BY – Group rows with similar values
πŸ”Ή HAVING – Filter aggregated results

πŸ”— Working with Multiple Tables

πŸ”Ή JOIN – Combine data from multiple tables

⚑ Performance

πŸ”Ή INDEX – Speeds up data retrieval in large tables

πŸ“Œ Tip:
Mastering these fundamentals makes solving complex SQL problems much easier.

πŸ”₯ Try this today:
Pick one command and write a small query to practice it.

🚨 Quick SQL Reality Check

Most developers think:

COUNT(*) = COUNT(Column)

But that’s not always true πŸ‘€

A single NULL value can completely change the result.

I recorded a quick 30-second Short explaining the difference with a simple example.

πŸŽ₯ Watch here:
πŸ‘‰ [Paste YouTube Shorts Link]

Trust me, this is one concept worth remembering for SQL interviews and real-world projects.

Or, if you want something more aggressive:

⚠️ SQL Interview Trap

What will these return?

COUNT(*)

COUNT(Salary)

Same answer? πŸ€”

Most people get this wrong because of NULL values.

I explained it in a quick YouTube ShortπŸ‘‡
