The Recruitment Process cosisted of 4 rounds :

1. Screening Test on Hackerrank - 80 minutes - 10 MCQs - 2 Coding questions (LeetCode Easy diffciculty)
2. Technical Round 1
3. Technical Round 2
4. Managerial Round

The technical rounds and managerial rounds were completed on same day.

Technical Round 1:
The interview was taken by MTS -3 (5+ years experience) guy.The interview lasted for approx 1 hr. Very friendly and polite. He asked me to code the solution of 2 problems.

1. A list/array/vector of string is given. return the first index of repeating elements. The problem was quite straight-forward . I gave him a brute-force solution using 2 for loops.
2. The 2nd Problem was standard Parentheses Balance. I wrote the satndard stack solution. We then discussed its corner cases.

Technical Round 2:
The Interview was taken by Senior Technical Manager (11 years experince). He was polite and very knowledgable with basic concepts. The Interview lasted for around 1 hr.

1. Definition of Classes and Objects with relevant examples.
2. What are static variables
3. What is use of PostgreSQL
4. Write a code to check whether anagram of given string is palindrome or not.
5. Test Sceanrio for calculater
6. Test Scenario for Google Login Page
7. Puzzle about 9 identical coins where 1 coin is of slightly higher weight.
8. TCP vs UDP

I answered almost all the questions.

Solution for Code :

bool solve (string st)
{
vector <int> fq(26,0);
int count = 0;

for(char x: st)
{
fq[x-'a']++;
}

for(int i =0;i<26;i++)
{
if(fq[i]%2!=0)
	count++;
	
}

return (count==0 || count==1)?true:false;
}

The Core logic of the solution is that in a palindromic string every charater has to occur in multiples of 2 except the central(element in the middle of a odd length string) character.

Managerial Round:
It was taken by another senior technical manager (14 years experience). Very humble and polite. This round consisted of behavioural questions. He also shared his industry experince and discussed about job profile and work culture in company. we also talked about salary expecations and joining dates.

Overall, this was an enriching experience. These guys walked an extra mile to make me feel comfortable.
