Testing is the process of evaluating a software application to ensure it meets specified requirements and functions correctly.
Testing involves executing the software with the intent of finding bugs or errors.
Types of testing include unit testing, integration testing, system testing, and acceptance testing.
Testing can be manual or automated, with automated testing using tools like Selenium or JUnit.
Regression testing en...
SQL joins queries are used to combine rows from two or more tables based on a related column between them.
Use INNER JOIN to return rows when there is at least one match in both tables
Use LEFT JOIN to return all rows from the left table and the matched rows from the right table
Use RIGHT JOIN to return all rows from the right table and the matched rows from the left table
Use FULL JOIN to return rows when there is a match
Lack of relevant experience, tough competition, and limited job opportunities in desired field.

I once tried to bake a cake but accidentally used salt instead of sugar.
Confused salt with sugar while baking
Realized mistake after tasting batter
Had to start over with new ingredients
I applied via Campus Placement and was interviewed in Jul 2024. There were 5 interview rounds.
The 2nd round is GD: The GD was conducted properly for other batches. But for our batch the HR just collected everyone's resume and asked qns from our resume.
(Note: This is not an elimination round)
The 3rd round was Aptitude and Technical mcq test: 10 qns - DBMS, 20 - Quants, 20 - Java mcq
(Note: This round has negative markings)
Reverse a string in Python using slicing
Use string slicing with a step of -1 to reverse the string
Example: 'hello'[::-1] will return 'olleh'
I appeared for an interview in May 2022.
Explanation of differences between union and union all, stored procedures and functions, primary key and foreign key, and temp tables.
Union combines and removes duplicates, while union all combines without removing duplicates.
Stored procedures are precompiled and can return multiple result sets, while functions are not precompiled and can only return a single value.
Primary key uniquely identifies a record, while foreig...

I applied via LinkedIn and was interviewed in Nov 2020. There were 4 interview rounds.
I applied via Naukri.com and was interviewed in Aug 2020. There were 5 interview rounds.
Interfaces define a contract for classes to implement certain methods and properties.
Interfaces allow for polymorphism and loose coupling.
Classes can implement multiple interfaces.
Interfaces cannot be instantiated on their own.
Interfaces can have default method implementations.
Interfaces can be used to enforce design patterns like the adapter pattern.

SQL command for creating a table
Use CREATE TABLE statement
Specify table name and column names with data types
Add any constraints or indexes as needed
SQL commands for inserting, updating, and deleting data from a table.
INSERT INTO table_name (column1, column2, column3) VALUES (value1, value2, value3);
UPDATE table_name SET column1 = new_value1 WHERE condition;
DELETE FROM table_name WHERE condition;
Truncate and drop are SQL commands used to remove data from a table.
Truncate removes all data from a table but keeps the structure intact.
Drop removes the entire table and its structure.
Truncate is faster than drop as it only removes data.
Drop cannot be undone while truncate can be rolled back.
Truncate resets the identity of the table while drop does not.
Examples: TRUNCATE TABLE table_name; DROP TABLE table_name;
C++ is an extension of C with object-oriented programming features.
C++ supports classes and objects while C does not.
C++ has better support for polymorphism and inheritance.
C++ has a standard template library (STL) while C does not.
C++ allows function overloading while C does not.
C++ has exception handling while C does not.

Network layers are a hierarchical way of organizing communication protocols.
Network layers provide a modular approach to networking.
Each layer has a specific function and communicates with adjacent layers.
The OSI model has 7 layers, while the TCP/IP model has 4 layers.
Examples of layers include the physical layer, data link layer, network layer, transport layer, and application layer.
Deadlock is a situation where two or more processes are unable to proceed because they are waiting for each other to release resources.
Occurs in multi-threaded/multi-process environments
Can lead to system freeze or crash
Prevention techniques include resource ordering and timeouts
Example: Process A holds resource X and waits for resource Y, while Process B holds resource Y and waits for resource X
Paging and Segmentation are memory management techniques used by operating systems.
Paging divides memory into fixed-size pages and stores them in physical memory.
Segmentation divides memory into logical segments and stores them in physical memory.
Paging allows for efficient use of physical memory and reduces fragmentation.
Segmentation allows for protection and sharing of memory between processes.
Examples of operating s...
Reverse a linked list using iterative and recursive methods.
Iterative method involves traversing the list and changing the pointers to reverse the order.
Recursive method involves calling the function recursively on the next node and changing the pointers.
Both methods have O(n) time complexity and O(1) space complexity.
Example: 1->2->3->4->5 becomes 5->4->3->2->1.
Clone a linked list with a random pointer.
Create a new node for each node in the original list.
Use a hash table to map the original nodes to their clones.
Iterate through the original list again and update the random pointers of the clone nodes.
