I was interviewed before Feb 2024.
There were two coding questions; one was related to linked lists, and the other was linked to binary trees.
Developed a web application for tracking inventory and sales data
Used React for front-end development
Implemented RESTful APIs using Node.js and Express for back-end

Reversing a linked list involves changing the direction of pointers to go from the end to the beginning.
Start by initializing three pointers: current, previous, and next.
Iterate through the linked list, updating the pointers to reverse the direction of the links.
Update the head of the linked list to point to the new first node, which was the original last node.
Program to find perfect squares between two numbers
Iterate through numbers between the given range
Check if the square root of the number is an integer
If yes, then it is a perfect square
Smart pointers in C++ are objects that act like pointers but provide automatic memory management.
Smart pointers help prevent memory leaks by automatically managing memory allocation and deallocation.
Examples include unique_ptr, shared_ptr, and weak_ptr.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to prevent circular references.
Mutual exclusion is a concept in concurrent programming where only one thread can access a shared resource at a time.
Ensures that only one thread can access a critical section of code at a time
Prevents race conditions and data corruption
Commonly implemented using locks, semaphores, or mutexes
Example: Using a mutex to protect a shared variable in a multi-threaded application
Implementing multithreading involves creating and managing multiple threads to execute tasks concurrently.
Identify the tasks that can be executed concurrently
Create and manage multiple threads to execute these tasks simultaneously
Use synchronization techniques like locks and semaphores to prevent race conditions
Handle communication and coordination between threads
Consider thread safety and resource sharing issues

I applied via Company Website and was interviewed in Dec 2019. There were 4 interview rounds.
Explanation of row number, rank, dense rank, partition by, indexing joins, and query optimization techniques.
Row number is a function that assigns a unique number to each row in a result set.
Rank is a function that assigns a rank to each row based on the values in a specified column.
Dense rank is a function that assigns a rank to each row based on the values in a specified column, but with no gaps in the ranking.

I applied via Approached by Company and was interviewed before Jul 2021. There were 7 interview rounds.
I applied via Naukri.com and was interviewed in Nov 2024. There was 1 interview round.
Union combines the results of two or more SELECT statements, while Union all includes all rows, including duplicates.
Union removes duplicate rows from the result set, while Union all includes all rows.
Union sorts the result set, while Union all does not.
Union is slower than Union all because it performs a distinct operation.
Example: SELECT column1 FROM table1 UNION SELECT column1 FROM table2;
Example: SELECT column1 FRO
Joins are generally faster than unions.
Joins are typically faster than unions because they combine data from multiple tables based on a common column, while unions combine data from multiple queries into a single result set.
Joins can utilize indexes on the columns being joined, which can improve performance.
Unions involve combining the results of multiple queries, which can be slower as it requires merging and sorting ...

MCQ based on programming, 2 programming problems
Copy constructor is a special constructor that creates a new object by copying an existing object.
It is used to initialize an object with another object of the same class.
It takes a reference to an object of the same class as an argument.
It creates a new object with the same values as the object passed as argument.
It is automatically called when a new object is created from an existing object.
Example: MyClass obj1; MyC
Shallow copy creates a new object with the same reference as the original, while deep copy creates a new object with a new reference.
Shallow copy only copies the top-level object, while deep copy copies all nested objects.
Shallow copy is faster and uses less memory, while deep copy is slower and uses more memory.
Examples of shallow copy include copying arrays and objects using the spread operator, while examples of dee...
Implementation of Merge Sort on an array

Recursively sort the two halves
Merge the sorted halves
Time complexity: O(n log n)
Space complexity: O(n)
Virtual functions are functions that can be overridden by derived classes.
Virtual functions are declared in a base class and can be overridden in derived classes.
They allow for polymorphism, where a derived class object can be treated as a base class object.
Virtual functions are called based on the actual object type, not the pointer or reference type.
They are declared using the virtual keyword in the base class and ca...
