Matrix Bit Flipping Problem
In this task, you're provided with a binary square matrix of size 'N * N' named
MAT. The task requires you to perform row and column flips whenever a zero (0) is encountered in... - Ans.
I first applied brute force but the solution was exceeding the time limit so I looked for ways to avoid traversing every
row and column of the matrix. Take the input of the matrix and in a map stored the location of every 0 in the original matrix. Then I traversed through the matrix whenever I encountered a 0 I traversed through its row and column and counted the number of ones. I also marked the row and column visited ... - Q2.
Jump Game Problem Statement
In this problem, you are given an array
ARRconsisting ofNintegers. Your task is to determine the minimum number of jumps required to reach the last index of the arrayN - 1.... - Ans. Brute Force Approach
- For each index, we find all possible locations we can jump to i.e if we are currently at an index ’i’ and ‘ARR[i]’ = k then we recursively find the answer for all indices from i + 1 to i + k and take the minimum of the answer and add 1 to it to find the minimum number of jumps to reach index last index from index ‘i’.

It was an interview round that took place over skype and it lasted for about 45 minutes. My interviewer was polite and gave me time to think for a few answers and was patient when there were technical difficulties. I was also asked to share my screen and show the working code for a few of the questions asked in the interview. I used an online compiler to do so (onlinegdb). Overall the interview went pretty decent with a mix of easy and tough questions.
- Q1. Write a SQL query to select all the people who are below the age of 75 from a set of people.

It was the last round. 15 students were selected for this round. I was tired since I already gave 2 interviews.
Interview Preparation Tips
Tip 1 : Having proper knowledge over Data Structures and Algorithms is crucial. Have your concepts cleared and then select one coding platform( for example, leetcode, CodeZen, GeeksForGeeks) and try to practice at least 5 questions everyday topic-wise. I completed around 300+ questions on leetcode, 100+ questions on geeks for geeks and around 30-40 problems on InterviewBit.
Tip 2 : Focus on time and space complexity. Students usually ignore this fact. However, you should think about how you can optimize your code further. Hence, instead of trying to solve more problems, try to analyze it.
Tip 3 : It sometimes gets easy to demotivate but you need to keep practicing daily. Don't cut down your sleep and diet. Healthy lifestyle and personality development also plays a crucial part.
Tip 1 : Do not mention those skills, projects or achievements which you haven't achieved. The interviewer is intelligent enough to verify them.
Tip 2 : Do not keep your resume too long, and do not mention irrelevant details. One page resume for an intern is enough.
Tip 3 : Have projects related to the field which you are applying for, this shows you are already experienced in the field.

Remove the Kth Node from the End of a Linked List
You are given a singly Linked List with 'N' nodes containing integer data and an integer 'K'. Your task is to delete the Kth node from the end of this Lin...
- Ans. Using Lists
The naive solution is to process all the nodes from the front side of the linked list and keep adding a node to the list. Now we can easily remove the Kth node from the end of the list by simply replacing the next pointer of the ('LENGTH' - 'K' - 1)th node (0-based indexing from start) of the list with the ('LENGTH' - 'K' + 1)th node. This way we can remove the Kth node from the end of the linked list.
