Selected Interview preparation journey
Preparation
Duration: 2 months
Topics: 1. Data Structure and algorithms (arrays, queue, stack, LinkedList, Dynamic programming, Graph,Trees) 2. DBMS 3.System Design(might not be asked to freshers) 4. Core and advanced Java 5. Computer Networks (not much)6. Operating Systems
Tip 1 : Make you Data Structure and algorithms , Problem solving strong ( use to do some dsa problems on code studio and leetcode daily.
Tip 2 : Practiced Quality questions and mostly asked questions list available on codestudio( used company tags and topic tags) as quality matters more than quantity of questions .
Tip 3 : Give mock interviews, this really helped me as it gives you clearity and builds confidence.
Tip 4 : Read respective company’s interview experiences available on codestudio and other websites before going to actual interview, as this gives you idea about level of interviews and you can prepare beforehand.
Tip 5 : after solving dsa problem .Try to look in discussion section too as you can get more optimised or more efficient approach used by others to solve the problem.
Tip 6 : Prepare important concepts from Operating system,DBMS,System design too as that might also be asked.
Tip 7 : Do atleast 2 quality projects.
Not a Tip But : Lot of quality content available online, whenever felt like stuck with some concepts take help from senior or colleagues ( I use to watch coding ninja shorts by parikh jain whenever felt demotivated or stuck with concepts)
Application process
Where: Naukri
Eligibility: 1+year of experience with java
Tip 1 : Have a concise resume , don't fill your resume with unnecessary details like your address, relationship status etc.

1. Longest Palindromic Substring

Asked in companies
You are given a string 'str' of length 'N'.
Your task is to return the longest palindromic substring. If there are multiple strings, return any.
A substring is a contiguous segment of a string.
For example :
str = "ababc"
The longest palindromic substring of "ababc" is "aba", since "aba" is a palindrome and it is the longest substring of length 3 which is a palindrome.
There is another palindromic substring of length 3 is "bab". Since starting index of "aba" is less than "bab", so "aba" is the answer.
Problem approach
The Basic approach is to check each substring whether the substring is a palindrome or not. To do this first, run three nested loops, the outer two loops pick all substrings one by one by fixing the corner characters, the inner loop checks whether the picked substring is palindrome or not. The optimal approach would be to use Dynamic programming in which we can maintain a 2D matrix that is filled in bottom-up manner. The value of 2D matrix will be true, if the substring is a palindrome, otherwise false.Find the longest palindrome using this filled 2d matrix.
2. Java based Questions
Core Java questions were asked:
1. Explain String pool in Java.
2.What does the string intern() method do in Java?
3. Why String are immutable?
4.Difference between Mutex and Semaphores.
5. Serialization in java, Interface vs abstract classes and use cases.
6. Deadlocks and its prevention.
7. Difference between interface and functional interface.
8. OOps concept
9. Multithreading, Types of Thread.
10. What are the two ways of implementing thread in Java?(asked me to write code)
Problem approach
Think out loud. Ask interviews if you have any questions and doubts.
