Interview preparation journey

Journey

In my first year, I started learning programming, specifically C++. In my second year, I focused on learning DSA, which took about a year to master. In my final year, I studied other subjects such as OS, DBMS, and networking, and most importantly, I grasped OOP concepts.

Application story

I filled out the form sent by the placement cell, and after a few days, I received an email for an online assessment on September 6, 2022, which lasted about 90 minutes. After clearing the online assessment, I received a technical interview link for September 12, 2022, conducted on Superset.

Why selected/rejected for the role?

I got selected for this role because I was sufficiently skilled and well-prepared to crack both the online exam and the technical interview. I confidently answered all the questions they asked me during the interview.

Preparation

Duration: 8 months

Topics: Data Structures, Algorithms, OOPS, Database Management System, Networking

Tip

Tip 1: Start learning data structures at least a year before your placements.

Tip 2: Focus on OOP programs, including inheritance.

Tip 3: Make sure you learn everything about your project.

Application process

Where: Campus

Eligibility: Above 7 CGPA, 70%+ in intermediate

Resume tip

Tip 1: Mention only those things that you know.

Tip 2: Ensure you have at least two good projects.

Coding problem5

It was around 11 am on the morning of September 6, 2022. I was sitting alone in my room; both the assessment round and the interview round were conducted online.

1. Function to Move Hashes to the Front of a String

You have to write a function that accepts, a string whose length is “len”, the string has some “#”, in it you have to move all the hashes to the front of the string return the whole string and print it.

char* moveHash(char str[],int n);

Problem approach

Step 1:
Input: Move#Hash#to#Front
Output: ###MoveHashtoFront

Step 2: write moveHash()
char *moveHash(char str[],int n)
{
char str1[100],str2[100];
int i,j=0,k=0;
for(i=0;str[i];i++)
{
if(str[i]=='#')
str1[j++]=str[i];
else
str2[k++]=str[i];
}
strcat(str1,str2);
printf("%s",str1);
}

Step 3: write driver code
int main()
{
char a[100], len;
scanf("%[^\n]s",a);
len = strlen(a);
moveHash(a, len);
return 0;
}

2. PSUEDO CODE BASED QUESTIONS

What will be the space required for this piece of code?

int sum (int B[], int n)

{
int s = 0, j;

for (j = 0; j < n; j++)
s = s + B[i];
return s;

}
//Given that size of sizeof(int) = 2 bytes

Problem approach

The code will acquire a space of 2n+8.
There are n elements in the array and the int data type acquires 2 bytes, so there will be 2n bytes acquired.
The int array occupies 4 bytes.
The s variable will occupy 2 bytes.
The j variable will occupy 2 bytes.
so total=2n+4+2+2=2n+8 bytes

3. Puzzle

You’re giving a mathematical statement and you need to create a correct combination of digits, to make LHS = RHS. Note: One Digit may only be used once, in some cases all the digits may not be available.
?X?+?=20

Marking Scheme

Level Rewards = (Current-Level)2/(Time taken at Level)
Total Rewards = Σ (Rewards at each level)

Problem approach

Tip 1: There can be multiple solutions
First, we will try to solve it incorrectly
Tip 2: 2 x 9+2=20 would be incorrect because we can use only any digit only once
Tip 3: 7 x 2+6=20
3 X 4+8=20
6 x2+8=20

4. Program to Solve Polynomial Equation

Write a function to solve the following equation a3 + a2b + 2a2b + 2ab2 + ab2 + b3.

Write a program to accept three values in order of a, b and c and get the result of the above equation.

Problem approach

Step 1: initialize the variables
int a,b,c;
scanf("%d%d%d",&a,&b,&c);
int sum;
Step 2: use this expression
sum=(a+b)*(a+b)*(a+b);
printf("%d",sum);

5. Aptitude Question

A sum of Rs. 900 amounts to Rs. 950 in 3 years at simple interest. If the interest rate is increased by 4%, it would amount to how much?

Problem approach

Step 1:P=900
T=3
Step 2:SI= 900-950=50
R= 50 x 100/900 x 3 = 50/27
now the rate is increased by 4% and we have a rate % 50/27 ....so the new rate% is =50/27 + 4= 158/27
SI = (900 x 3 x 158)/ 100 x 27 = 158
Step 3 : since Si 158 and P =900 so new amount is 900+158= 1058

2. DBMS

What is a view in SQL? How to create a view? (Learn)

Problem approach

Tip 1: A view is a virtual table based on the result set of an SQL statement. We can create it using the create view syntax.
Tip 2:CREATE VIEW view_name AS
SELECT column_name(s)
FROM table_name
WHERE condition
