I applied via Campus Placement and was interviewed in Jul 2021. There were 3 interview rounds.
Polymorphism is the ability of an object to take on many forms.
It allows objects of different classes to be treated as if they were objects of the same class.
It is achieved through method overriding and method overloading.
Example: A parent class Animal can have child classes like Dog, Cat, and Cow. All of them have a common method called 'makeSound', but each of them makes a different sound.
Example: A method can be ove...
Asynchronous functions in JavaScript allow code to run without blocking other code from executing.
Asynchronous functions use callbacks or promises to handle the result of the function.
They are useful for tasks that may take a long time to complete, such as fetching data from a server.
Examples include setTimeout(), fetch(), and XMLHttpRequest().

Iterate through the array and for each element, check if the complement (S - current element) exists in a hash set.
If the complement exists, add the pair to the result list.
Sort the result list based on the criteria mentioned in the problem statement.

Given a matrix named UNIVERSE
with 3 rows and 'N' columns, filled with characters {#, *, .}, where:
The task is to identify constellations shaped like vowels within a matrix filled with characters {#, *, .}.
Iterate through the matrix to find 3x3 constellations shaped like vowels.
Check for vowels 'A', 'E', 'I', 'O', 'U' in each 3x3 constellation.
Print the vowels found in each constellation for each test case.

It was more like an HR+Tech round
Given a sorted array 'A' of 'N' integers, determine whether a number 'X' exists within this array for a series of queries. For each query, print 1 if 'X' exists in the ...
Search for a number in a sorted array and determine its existence for multiple queries.
Iterate through each query integer 'X' and perform binary search on the sorted array 'A' to check for its existence.
Output 1 if 'X' is found in 'A', otherwise output 0.
Ensure to handle multiple test cases as per the given constraints.

Interrupts are signals that temporarily halt the execution of a program to handle a specific event.
When an interrupt occurs in 8051, the program counter is saved on the stack and the interrupt service routine (ISR) is executed.
The ISR handles the interrupt and then returns control to the main program by restoring the program counter from the stack.
If an interrupt occurs while another interrupt is being serviced, the se...
The location of current line of execution is stored in the stack when there is an interrupt.
When an interrupt occurs, the processor saves the current state of execution on the stack.
The location of the current line of execution is stored in the program counter (PC) register.
The PC register is pushed onto the stack along with other registers.
After the interrupt is serviced, the processor pops the saved state from the st
Logic gates are basic building blocks of digital circuits. They perform logical operations on inputs to produce outputs.
AND gate: output is 1 only if both inputs are 1
OR gate: output is 1 if either input is 1
NOT gate: output is the opposite of the input
NAND gate: output is 0 only if both inputs are 1
NOR gate: output is 0 if either input is 1
XOR gate: output is 1 if inputs are different
XNOR gate: output is 1 if inputs a
Draw half adder and full adder without using EXOR gate.
Half adder can be implemented using AND and OR gates
Full adder can be implemented using two half adders and an OR gate
In half adder, sum is obtained by ORing two inputs and carry is obtained by ANDing two inputs
In full adder, sum is obtained by using two half adders and an OR gate, and carry is obtained by ANDing three inputs
Remove spaces from input string and return output string
Iterate through each character of the input string
If the character is not a space, add it to the output string
Return the output string
