Programming Concepts Interview Questions with Answers
1๏ธโฃ What is the difference between compiled and interpreted languages?
โ Compiled Language: Code is converted into machine code before execution. Faster performance. Examples: C, C++, Java (partially compiled)
โ Interpreted Language: Code executes line by line at runtime. Slower but easier debugging. Examples: Python, JavaScript
2๏ธโฃ What is OOP? Explain its 4 pillars
โ Object-Oriented Programming (OOP): A programming paradigm based on objects, classes, and real-world modeling.
๐น 4 Pillars:
1. Encapsulation: Wrapping data + methods together.
2. Abstraction: Showing only essential features.
3. Inheritance: One class acquires properties of another.
4. Polymorphism: Same function behaves differently.
3๏ธโฃ Difference between Abstraction vs Encapsulation
Abstraction hides implementation details, while Encapsulation protects data.
Abstraction focuses on what to show, Encapsulation focuses on how to restrict access.
4๏ธโฃ What is Polymorphism? Give a real example
โ Polymorphism = One interface, multiple behaviors. Same method performs different actions based on context.
๐ฏ Real Example: A person behaves differently: At home โ son, At office โ employee
5๏ธโฃ What is the difference between Stack and Heap memory?
Stack Memory stores function calls & local variables, automatically managed, and faster access.
Heap Memory stores objects & dynamic memory, manually or garbage collected, and slower access.
6๏ธโฃ What is Recursion? When should you avoid it?
โ Recursion: A function calling itself until a base condition is met.
๐ซ Avoid recursion when memory is limited, deep recursive calls are possible, or iterative solution is simpler.
7๏ธโฃ What is the difference between Pass by Value and Pass by Reference?
โ Pass by Value: Copy of variable passed, changes don't affect original.
โ Pass by Reference: Original variable reference passed, changes affect original.
8๏ธโฃ What are mutable vs immutable objects?
โ Mutable Objects: Can be changed after creation. Examples: List, Dictionary
โ Immutable Objects: Cannot be modified after creation. Examples: String, Tuple
9๏ธโฃ What is a Deadlock?
โ Deadlock: A situation where two or more processes wait for each other indefinitely.
10๏ธโฃ What is Multithreading?
โ Multithreading: Running multiple threads (tasks) simultaneously within a program. Benefits: Better performance, faster execution.

Most Asked SQL Interview Questions at MAANG Companies๐ฅ๐ฅ
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;

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;
