Selected Interview preparation journey
Journey
I got admission in Jadavpur University in 2018 in Electronics And Tele-Communication Engineering stream. I started preparing for Software roles in third year , learned programming languages c++, and java then learned DSA, OOPS concepts , OS, DBMS, MySql. Companies started to visit college in final year and I got shorlisted clearing the coding round for the company L&T, got rejected in interview round. After that I got shortlisted for Wipro Turbo and got selected in final round . I had the offer from wipro and later I applied from offcampus for Publicis Sapient's ASDE 1 profile, cleared exam round followed by interview round and got selected for the offer.
Application story
Publicis Sapient visited our college but was not allowed to sit for the placement as I was already placed in Wipro , So I applied for it through off Campus
Why selected/rejected for the role?
As I solved both of the questions in coding round I got the chance for interview . In interview round I manged to answer most of the questions asked by the interviewer.In interview also I was asked to code two algorithms which I was able to code.

Asked in companies
You are given a city which contains 'N' x 'M' houses, where each house can have one of the following three conditions :
1. The value ‘0’ represents an empty house,
2. The value ‘1’ represents a non-infected person,
3. The value ‘2’ represents an infected person.
It takes one day to propagate the infection from an infected house to its adjacent (Front, Back, Left, Right) non-empty and non-infected house. An empty house can only break the line of propagation of infection.
You need to return the minimum number of days Covid will take to infect each and every house in the city. And for the God’s sake if this is impossible, return -1 instead.

Given a singly linked list of integers. Your task is to return the head of the reversed linked list.
For example:
The given linked list is 1 -> 2 -> 3 -> 4-> NULL. Then the reverse linked list is 4 -> 3 -> 2 -> 1 -> NULL and the head of the reversed linked list will be 4.
Follow Up :
Can you solve this problem in O(N) time and O(1) space complexity?
Problem approach
step 1 : created sample linked list using object of node class containing data, and the next pionter
step 2 : paassed the root node to the function I wrote to reverese using recursion method
