I applied via Campus Placement and was interviewed in Jun 2022. There were 3 interview rounds.
In simform Interview Aptitude test is just a common test which contains all types of questions it includes reasoning, aptitude, c language pseudocode and verbal ability questions. Questions are easy to moderate not so difficult.
Simform coding test is having 5 coding problems. Which includes simple array and DSA related problems . 3 problems are easy to moderate . 1 or 2 problems they give little bit hard . They ask a big SQL query also as a coding problem in that 5 problems . You have to solve atleast 3 or more problems to comfortably pass coding round .
Abstract class can have implementation while interface cannot. A class can implement multiple interfaces but only extend one abstract class.
Abstract class can have constructors while interface cannot.
Abstract class can have non-abstract methods while interface can only have abstract methods.
A class can implement multiple interfaces but only extend one abstract class.
Abstract class can have instance variables while inte...
Arrow functions are a concise way to write functions in JavaScript.
Arrow functions have a shorter syntax compared to regular functions.
They do not have their own 'this' value, instead, they inherit 'this' from the surrounding context.
Arrow functions are always anonymous and cannot be used as constructors.
They are commonly used in React components for event handlers and callback functions.
Primary key uniquely identifies a record in a table, while unique key ensures that all values in a column are distinct.
Primary key is used to enforce entity integrity, while unique key enforces domain integrity.
A table can have only one primary key, but multiple unique keys.
Primary key can't have null values, while unique key can have null values.
Primary key is automatically indexed, while unique key may or may not be
To join three different tables in SQL, you can use the JOIN keyword along with the appropriate join conditions.
Use the JOIN keyword to combine tables based on a common column
Specify the join conditions using the ON keyword
You can join more than two tables by chaining multiple JOIN statements
Different types of joins include INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL JOIN
Interfaces in Java provide a way to achieve abstraction and multiple inheritance.
Interfaces define a set of methods that a class must implement.
They allow for loose coupling between classes.
Interfaces can be used to achieve polymorphism.
Java does not support multiple inheritance, but interfaces provide a way to achieve it.
Interfaces are used extensively in Java frameworks like Spring and Hibernate.
Encapsulation is a mechanism of wrapping data and code acting on the data together as a single unit.
Encapsulation is used to hide the implementation details of an object from the outside world.
It helps in achieving data abstraction and data hiding.
In Java, encapsulation is achieved by declaring the variables of a class as private and providing public getter and setter methods to access and modify the data.
Example: A ba...
Yes, exception handling is required in a big project.
Exception handling helps in identifying and resolving errors during runtime.
It improves the stability and reliability of the application.
Exceptions can occur due to various reasons like network issues, server errors, or user input errors.
Handling exceptions gracefully prevents the application from crashing and provides a better user experience.
It allows for proper er...

I have always been passionate about learning and expanding my knowledge in the field of frontend development.
Pursuing a master's degree in a foreign country will provide me with a global perspective and exposure to diverse cultures.
I believe that studying abroad will enhance my skills and make me a more well-rounded developer.
I have researched various universities...
Overloading is having multiple methods with the same name but different parameters. Overriding is implementing a method in a subclass that already exists in the parent class.
Overloading is compile-time polymorphism while overriding is runtime polymorphism.
Overloading is used to provide different ways of calling the same method with different parameters.
Overriding is used to provide a specific implementation of a method...
Access specifiers in Java are keywords that determine the visibility of a class, method, or variable.
There are four access specifiers in Java: public, private, protected, and default.
Public: accessible from anywhere in the program.
Private: accessible only within the same class.
Protected: accessible within the same class, subclasses, and same package.
Default: accessible within the same package only.

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
