Interview preparation journey
Journey
I joined my Btech after giving the Jee exam. At first, I was unaware of coding then after two years, my seniors told me this was the only way to crack big companies. Then I started practicing coding from the different websites.
Application story
This company visited our campus for placement. It allowed the first to take an online assessment and, on that basis, make the selection.
Why selected/rejected for the role?
I was rejected because i was not able to solve the last question asked in 2nd round .
Preparation
Duration: 4 months
Topics: Data Structures, Algorithms, OOPs, DBMS, SQL, Web Development
Tip 1 : Do not rush into things. Learning takes time. Focus should be on the concepts and not just on leaving topics half-prepared. Devote 70% of both time and effort to DSA. I solved a total of around 500 questions on sites like GFG and Leetcode. Do not repeat similar questions just to increase the count of the number of questions
Tip 2 : Competitive Programming is a bonus and not a necessity, rather focus on core DSA based problems before trying CP. Do not pursue CP if you do not like it. Devote that extra time to core CS subjects and aptitude preparation.
Tip 3 : Projects play an important role too, do no ignore them. Try to get your hands dirty with a little bit of every field i.e., frontend, backend, and database.
Application process
Where: Campus
Eligibility: Above 7 CGPA
Tip 1 : Have some projects on resume.
Tip 2 : Do not put wrong things on resume.

1. Check If The String Is A Palindrome
Easy
10m average time
90% success
0/40
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
Given a string, determine if it is a palindrome, considering only alphanumeric characters.
2. Coin Change(Finite Supply)
Hard
0/120
Asked in companies
You are given an array of integers ‘coins’ denoting the denomination of coins and another array of integers ‘freq’ denoting the number of coins of each denomination.
You have to find the number of ways to make the sum ‘V’ by selecting some(or all) coins from the array.
The answer can be very large. So, return the answer modulo 1000000007.
For Example :
‘N’ = 3, ‘coins’ = {1, 2, 3}, ‘freq’ = {1, 1, 3}, ‘V’ = 6
For the given example, we can make six by using the following coins:
{1, 2, 3}
{3. 3}
Hence, the answer is 2.

3. DBMS Questions
What is RDBMS?
.
Problem approach
RDBMS stands for Relational Database Management Systems. It is used to maintain the data records and indices in tables. RDBMS is the form of DBMS which uses the structure to identify and access data concerning the other piece of data in the database. RDBMS is the system that enables you to perform different operations such as- update, insert, delete, manipulate and administer a relational database with minimal difficulties. Most of the time RDBMS use SQL language because it is easily understandable and is used for often
4. DBMS Question
How many types of database languages are?
Problem approach
There are four types of database languages:
Data Definition Language (DDL) e.g., CREATE, ALTER, DROP, TRUNCATE, RENAME, etc. All these commands are used for updating the data that?s why they are known as Data Definition Language.
Data Manipulation Language (DML) e.g., SELECT, UPDATE, INSERT, DELETE, etc. These commands are used for the manipulation of already updated data that's why they are the part of Data Manipulation Language.
DATA Control Language (DCL) e.g., GRANT and REVOKE. These commands are used for giving and removing the user access on the database. So, they are the part of Data Control Language.
Transaction Control Language (TCL) e.g., COMMIT, ROLLBACK, and SAVEPOINT. These are the commands used for managing transactions in the database. TCL is used for managing the changes made by DML.

1. Closest Distance Pair
Easy
20m average time
0/40
Asked in companies
You are given an array containing 'N' points in the plane. The task is to find out the distance of the closest points.
Note :
Where distance between two points (x1, y1) and (x2, y2) is calculated as [(x1 - x2) ^ 2] + [(y1 - y2) ^ 2].
Problem approach
Given n (x,y) coordinates on a 2D plane Find the distance between the closest points.
2. Palindrome Linked List
Easy
20m average time
90% success
0/40
Asked in companies
You are given a singly Linked List of integers. Your task is to return true if the given singly linked list is a palindrome otherwise returns false.
For example:
The given linked list is 1 -> 2 -> 3 -> 2-> 1-> NULL.
It is a palindrome linked list because the given linked list has the same order of elements when traversed forwards and backward.
Follow Up:
Can you solve the problem in O(N) time complexity and O(1) space complexity iteratively?
Problem approach
You are given a singly Linked List of integers. Your task is to return true if the given singly linked list is a palindrome otherwise returns false.
