Selected Interview preparation journey
Journey
To secure a position in a company, it's crucial to have proficiency in coding and a solid understanding of key subjects such as Networking, DBMS, System Design, and Operating Systems. I began learning the basics of coding and a few Data Structures and Algorithms (DSA) topics like arrays, linked lists, queues, stacks, and searching/sorting in C++ during my school years (11th and 12th grade). Upon entering college, I furthered my skills by practising questions on coding platforms. In my third year of college, I deepened my understanding of DSA concepts by following tutorials on YouTube. Additionally, during the same year, I learned Database Management Systems (DBMS) a website.
Application story
This company is brought to us by the college. The college used to send emails to fill out forms for particular companies, requesting basic details.
Why selected/rejected for the role?
I got selected because I had enough knowledge of coding and was confident. Also, my communication skills were good.
Preparation
Duration: 11 months
Topics: Data Structures, DBMS, OOPS, Operating System, Algorithms, Networking, Web development
Tip 1: Begin with the basics of Data Structures and Algorithms (DSA) using C++.
Tip 2: Prioritize coding and DSA in your learning journey.
Tip 3: If you excel in web development, allocate more time to it rather than competitive programming (CP).
Application process
Where: Campus
Eligibility: 75% and above in 12th, above 7 CGPA
Tip 1: Projects are most important.
Tip 2: The skills set should be there, but not the false one.

The function/method calculateMatrixSum returns an integer representing the sum of odd elements of the given matrix whose ith and ith index are the sameThe function/method calculateMatrixSum accepts three arguments-rows an integer representing the number of rows of the given matrix, columns, an integer representing the number of columns of the given matrix and matrix, representing a two-dimensional array of integers. The function/method calculateMatrixSum compiles successfully but fails to return the desired result for some test cases due to logical errors. Your task is to fix the code so that it passes all the test cases.
Problem approach
This will explain explain
class Main {
static int calculateMatrixSum(int matrix[][], int m, int n)
{
int i,j,sum=0,row=m, column=n;
if((row>0)&&(column>0))
{
for(i=0;i {
for(j=0;j {
if(i==j)
{
if( matrix[i][j] % 2 != 0)
sum+=matrix[i][j];
}
}
}
}
return sum;
}
public static void main (String[] args) {
Scanner sc=new Scanner(System.in);
int rows=sc.nextInt();
int columns=sc.nextInt();
int twoD[][]=new int[rows][columns];
for(int i=0; i
{
for(int j=0; j
{
twoD[i][j]=sc.nextInt();
}
}
System.out.println(calculateMatrixSum(twoD,rows,columns));
}
}
2. Replace Each Element Of Array With Its Corresponding Rank

The function/method maxReplace prints space-separated integers representing the input list after replacing all elements of the input list with the maximum element of the input list. The function/method maxReplace accepts two arguments-size, an integer representing the size of the input list and inputList, a list of integers representing the input list, respectively. The function/method maxReplace compiles unsuccessfully due to a compilation error. Your task is to debug the code so that it passes all the test cases.
Problem approach
Step 1. read question carefully
Step 2: you easily find solution if u done leetcode

Coding problem3
It was October 13, 2022, around 2 PM. I had an interview call on Google Meet, and I was sitting alone in my PG room. I closed the door to ensure nobody could come behind my camera, so I had complete privacy. The interviewer was skilled, demonstrating excellent observation and listening abilities.
1. N-th Fibonacci Number
Moderate
40m average time
70% success

Asked in companies
Write code in your preferred language of printing Fibonacci Sequence, is a sequence where the next term is the sum of the previous two terms.
Problem approach
1. initialize first and second terms with 0 and 1
2. initialize the next term (3rd term) sum of above 2
3. print the first two terms t1 and t2 say
4. print 3rd to nth terms using loop
2. DBMS
What is atomicity?
Problem approach
Tip 1: These are basic theoretical questions.
Tip 2: You can prepare them 1-2 months before your placement starts.
Tip 3: Atomicity is a property of database transactions that ensures that a set of database operations either all occur, or none occur.
3. DBMS
What is normalization in DBMS and their types?
Problem approach
Tip 1:Normalization is used to minimize the redundancy from a relation or set of relations. It is also used to eliminate undesirable characteristics like Insertion, Update, and Deletion Anomalies.
Tip 2:Normalization divides the larger table into smaller and links them using relationships.
Tip 3:Types are
1NF
2NF
3NF
BCNF
