I was interviewed in May 2024.
I applied via Naukri.com and was interviewed in Dec 2021. There were 4 interview rounds.
The aptitude test was comprising of questions related to qualitative and quantitative reasoning along with basic computer science questions and coding questions also.
Java has automatic memory management, so pointers are not needed.
Java has a garbage collector that automatically manages memory.
Pointers can lead to memory leaks and security vulnerabilities.
C and C++ are low-level languages that require manual memory management.
Access modifiers control the visibility and accessibility of class members.
Public: accessible from anywhere
Private: accessible only within the class
Protected: accessible within the class and its subclasses
Default: accessible within the same package
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It is achieved through method overriding and method overloading.
Examples include function overloading, operator overloading, and inheritance.
Polymorphism helps in achieving loose coupling and flexibility in code design.
I applied via Campus Placement and was interviewed in Jan 2021. There were 5 interview rounds.
Method overloading, constructor, and normalization are all concepts in software development.
Method overloading allows multiple methods with the same name but different parameters.
A constructor is a special method used to initialize objects.
Normalization is the process of organizing data in a database to reduce redundancy and improve efficiency.
Inheritance is a mechanism in OOP where a new class is derived from an existing class.
Types of inheritance: single, multiple, multilevel, hierarchical, hybrid
Single inheritance: A derived class inherits from a single base class
Multiple inheritance: A derived class inherits from multiple base classes
Multilevel inheritance: A derived class inherits from a base class, which in turn inherits from another base class
Hierarch...

Round duration - 60 minutes
Round difficulty - Easy
This was an easy round which went really smooth.
Calculate the Nth term in the Fibonacci sequence, where the sequence is defined as follows: F(n) = F(n-1) + F(n-2)
, with initial conditions F(1) = F(2) = 1
.
Calculate the Nth Fibonacci number efficiently using dynamic programming.
Use dynamic programming to store previously calculated Fibonacci numbers to avoid redundant calculations.
Start with base cases F(1) and F(2) as 1, then iteratively calculate F(n) using F(n-1) and F(n-2).
Ensure the input N is within the constraints 1 <= N <= 10000.
Example: For N = 5, the 5th Fibonacci number is 5 (1, 1, 2, 3, 5).
Given a positive integer N
, your task is to determine and return all prime numbers less than or equal to N
.
N = 10
2 3 5 7
N = 20
Implement a function to return all prime numbers less than or equal to a given positive integer N.
Create a function that takes a positive integer N as input
Iterate from 2 to N and check if each number is prime
Use a helper function to determine if a number is prime
Return an array of all prime numbers less than or equal to N
A merge join in SQL is a method of combining two sorted datasets by matching corresponding rows based on a specified condition.
Merge join is used when joining two large datasets that are already sorted.
It is more efficient than other join methods like nested loop join or hash join for sorted datasets.
The join condition must be an equality condition.
Example: SELECT * FROM table1 INNER JOIN table2 ON table1.id = table2.i

Implement a function to multiply two sparse matrices and return the resulting matrix.
Create a function that takes two sparse matrices as input and returns the resulting matrix after multiplication
Iterate through the non-zero elements of the matrices to perform the multiplication efficiently
Handle the edge cases such as empty matrices or matrices with all zero elements
Ensure the dimensions of the matrices are compatible

Count the number of even or odd numbers in a range of an array based on given queries.
Create an array to store the input numbers.
Iterate through the queries and update or count even/odd numbers based on the query type.
Output the count of even or odd numbers for each query of type 1 or 2.
Round duration - 30 minutes

Altering columns in databases involves modifying the structure of a table by adding, deleting or modifying columns.
Use ALTER TABLE statement to modify columns
Add new columns using ADD COLUMN
Delete columns using DROP COLUMN
Modify columns using MODIFY COLUMN
Changing column data type may result in data loss

Generic collections provide type safety and reusability in software development.
Generic collections allow us to store and manipulate objects of any type in a type-safe manner.
They provide compile-time type checking, reducing the chances of runtime errors.
They promote code reusability by allowing the same collection to be used with different types.
Generic collections improve performance by eliminating the need for boxin...
