Most Asked SQL Interview Questions at MAANG Companies๐Ÿ”ฅ๐Ÿ”ฅ

Preparing for an SQL Interview at MAANG Companies? Here are some crucial SQL Questions you should be ready to tackle:

1. How do you retrieve all columns from a table?

SELECT * FROM table_name;

2. What SQL statement is used to filter records?

SELECT * FROM table_name
WHERE condition;

The WHERE clause is used to filter records based on a specified condition.

3. How can you join multiple tables? Describe different types of JOINs.

SELECT columns
FROM table1
JOIN table2 ON table1.column = table2.column
JOIN table3 ON table2.column = table3.column;

Types of JOINs:

1. INNER JOIN: Returns records with matching values in both tables

SELECT * FROM table1
INNER JOIN table2 ON table1.column = table2.column;

2. LEFT JOIN: Returns all records from the left table & matched records from the right table. Unmatched records will have NULL values.

SELECT * FROM table1
LEFT JOIN table2 ON table1.column = table2.column;

3. RIGHT JOIN: Returns all records from the right table & matched records from the left table. Unmatched records will have NULL values.

SELECT * FROM table1
RIGHT JOIN table2 ON table1.column = table2.column;

4. FULL JOIN: Returns records when there is a match in either left or right table. Unmatched records will have NULL values.

SELECT * FROM table1
FULL JOIN table2 ON table1.column = table2.column;

4. What is the difference between WHERE & HAVING clauses?

WHERE: Filters records before any groupings are made.

SELECT * FROM table_name
WHERE condition;

HAVING: Filters records after groupings are made.

SELECT column, COUNT(*)
FROM table_name
GROUP BY column
HAVING COUNT(*) > value;

5. How do you calculate average, sum, minimum & maximum values in a column?

Average: SELECT AVG(column_name) FROM table_name;

Sum: SELECT SUM(column_name) FROM table_name;

Minimum: SELECT MIN(column_name) FROM table_name;

Maximum: SELECT MAX(column_name) FROM table_name;

Hope it helps :)

โœ… Data Scientists in Your 20s โ€“ Avoid This Trap ๐Ÿšซ๐Ÿง 

๐ŸŽฏ The Trap? โ†’ Passive Learning 
Feels like youโ€™re learning but not truly growing.

๐Ÿ” Example:
โฆ Watching endless ML tutorial videos
โฆ Saving notebooks without running or understanding
โฆ Joining courses but not coding models
โฆ Reading research papers without experimenting

End result? 
โŒ No models built from scratch 
โŒ No real data cleaning done 
โŒ No insights or reports delivered

This is passive learning โ€” absorbing without applying. It builds false confidence and slows progress.

๐Ÿ› ๏ธ How to Fix It: 
1๏ธโƒฃ Learn by doing: Grab real datasets (Kaggle, UCI, public APIs) 
2๏ธโƒฃ Build projects: Classification, regression, clustering tasks 
3๏ธโƒฃ Document findings: Share explanations like youโ€™re presenting to stakeholders 
4๏ธโƒฃ Get feedback: Post code & reports on GitHub, Kaggle, or LinkedIn 
5๏ธโƒฃ Fail fast: Debug models, tune hyperparameters, iterate frequently

๐Ÿ“Œ In your 20s, build practical data intuition โ€” not just theory or certificates.

Stop passive watching. 
Start real modeling. 
Start storytelling with data.

Thatโ€™s how data scientists grow fast in the real world! ๐Ÿš€

AI vs ML vs Deep Learning ๐Ÿค–

Youโ€™ve probably seen these 3 terms thrown around like theyโ€™re the same thing. Theyโ€™re not.

AI (Artificial Intelligence): the big umbrella. Anything that makes machines โ€œsmart.โ€ Could be rules, could be learning.

ML (Machine Learning): a subset of AI. Machines learn patterns from data instead of being explicitly programmed.

Deep Learning: a subset of ML. Uses neural networks with many layers (deep) powering things like ChatGPT, image recognition, etc.

Think of it this way:
AI = Science
ML = A chapter in the science
Deep Learning = A paragraph in that chapter.
