This was a Technical round. About 60 students were shortlisted for this round. There were two interviewers. First, they asked me to introduce myself. Then I was asked some concepts of OOPS. some questions from OS and DBMS. I was asked to write code to reverse a link list on the notepad and share my screen. Then I was asked about my projects and internship. There were some situational questions related to the internship. They asked me what I know about the company.
My interview took place in the morning at around 10:00 a.m. and lasted for about an hour.

Reverse a singly linked list of integers and return the head of the reversed linked list.
Iterate through the linked list and reverse the pointers to point to the previous node instead of the next node.
Use three pointers to keep track of the current, previous, and next nodes while reversing the linked list.
Update the head of the reversed linked list as the last node encountered during the reversal process.

It was a virtual interview and there was just one interviewer. The interviewer was really friendly. First of all, the interviewer introduced himself and also shared some facts about the company. Then he asked me to introduce myself. Then behavioral and situational questions were asked. Then he asked if I was comfortable with relocation. BlackRock has 2 locations that are Gurgaon and Mumbai.
Tip 1 : Revise Trees especially AVL trees and tree traversals as the major questions for data structures were from trees.
Tip 2 : Revise your OOPs concepts for the interview round.
Tip 3 : If you have done a project in development, make sure you know well about them.
Tip 1 : Mention only those things in your resume, you have knowledge about.
Tip 2 : A project in development is a plus.

A program to find prime numbers within a given range
Iterate through numbers in the given range
Check if each number is divisible by any number other than 1 and itself
If not divisible, it is a prime number
Count the number of ones in a given number using pseudo code
Initialize a count variable to 0
Iterate through each bit of the number and check if it is 1
Increment the count if the bit is 1
Return the count as the result
I applied via Campus Placement and was interviewed in Aug 2022. There were 3 interview rounds.
Technical MCQ and coding (medium)
This was long programing round. In this you need to design a application. First you need do ER or class diagram. Then you need code in any programing language but OOPS is prefered. They see is app is scalable and data modeling

The round consisted of 3 coding Questions and 20 Technical MCQs.
Given a number of ropes denoted as 'N' and an array containing the lengths of these ropes, your task is to connect the ropes into one single rope. The cost to connect two r...
The task is to find the minimum cost required to connect all the ropes by summing their lengths.
Iterate through the ropes and connect the two shortest ropes at each step to minimize cost
Use a priority queue to efficiently find the shortest ropes
Keep track of the total cost as you connect the ropes
Example: For input [4, 3, 2, 6], connect 2 and 3 (cost 5), then connect 4 and 5 (cost 9), then connect 9 and 6 (cost 15) for...

M * M = M
The first line cont...
Check if a given matrix is idempotent by verifying if M * M = M.
Iterate through the matrix and multiply it with itself to check if it equals the original matrix.
If the condition M * M = M is satisfied, then the matrix is idempotent.
If the condition is not satisfied, then the matrix is not idempotent.
Given an integer 'N', calculate and print the sum of the least common multiples (LCM) for each integer from 1 to N with N.
The sum is represented as:LCM(1, N) + LCM(2, N) + ....
Calculate and print the sum of least common multiples (LCM) for each integer from 1 to N with N.
Iterate from 1 to N and calculate LCM of each number with N
Add all the calculated LCM values to get the final sum
Return the sum for each test case

This round is a Long Coding Round. Every Candidate was assigned with a mentor who guides them, We were given a real-life scenario for which we have to construct a database with required tables. We should draw an ER Diagram to demonstrate the Database. After the Database Completion, We have to Start Coding the Application. The Design(like Placing the button or background colour) is not given much importance. They mainly test the practical knowledge of candidates in OOPS and expertise in a C, C++, Java, Android or any other language were OOPS Concepts can be applied.

Sort an array of 0s, 1s, and 2s in linear time complexity.
Use three pointers to keep track of 0s, 1s, and 2s while iterating through the array.
Swap elements based on the values encountered to sort the array in-place.
Time complexity of the algorithm should be O(N) where N is the size of the array.
