Interview preparation journey
Journey
First of all, I got selected for a Tier 2 college from there, my journey in coding started. I have done most of my coding in my final years only, but I till now regret that I should have started a little bit earlier. I practised mainly from Leetcode and Code Studio.
Application story
This company visited our campus for the placement. First, they took the online assessment. Later, they called us for the interview rounds.
Why selected/rejected for the role?
I was rejected because I was not able to give Automata/core subjects related answers excellently. I think that was the only reason for not selecting me.
Preparation
Duration: 3 months
Topics: Data Structures, Algorithms, System Design, Aptitude, OOPS
Tip 1 : Must do Previously asked Interview as well as Online Test Questions.
Tip 2 : Go through all the previous interview experiences from Codestudio and Leetcode.
Tip 3 : Do at-least 2 good projects and you must know every bit of them.
Application process
Where: Campus
Eligibility: Above 7 CGPA
Tip 1 : Have at-least 2 good projects explained in short with all important points covered.
Tip 2 : Every skill must be mentioned.
Tip 3 : Focus on skills, projects and experiences more.

Asked in companies
You are given a string 'S'. Your task is to check whether the string is palindrome or not. For checking palindrome, consider alphabets and numbers only and ignore the symbols and whitespaces.
Note :
String 'S' is NOT case sensitive.
Example :
Let S = “c1 O$d@eeD o1c”.
If we ignore the special characters, whitespaces and convert all uppercase letters to lowercase, we get S = “c1odeedo1c”, which is a palindrome. Hence, the given string is also a palindrome.
Problem approach
In the recursive approach, we will traverse the string from [0, N/2], where N is the length of the string.
While traversing, we will check if S[i] == S[N-i-1], and if it is equal, then we will continue with recursion calls. Else, we will return false.
If the output of the recursive function is true, then we will print "YES"; else, we will print "NO."
2. Find prime numbers
Easy

Asked in companies
You are given a positive integer ‘N’. Your task is to print all prime numbers less than or equal to N.
Note: A prime number is a natural number that is divisible only by 1 and itself. Example - 2, 3, 17, etc.
You can assume that the value of N will always be greater than 1. So, the answer will always exist.
Problem approach
We iterate from 2 to N.
For each number num, we check if it is prime or not. We use the following optimized approach to check if a given number is prime.
We loop through all numbers from 2 to (num)^½.
For every number in the loop, we check if it divides num.
If we find any number that divides num, we can say num is not prime.
If num is prime, we store it in the result vector/list.
Finally, we return the result vector/list.
