August 26, 2017
Posted by Rahul Jain

Recently I have appeared for Java developer interview at the Morgan Stanley, Mumbai. It was a Video conference interview. Here are the set of questions asked to me :  

  1. Tell me about your current project and your roles and responsibility.
  2. Write a java function to reverse a string using recursion
  3. Write a java program to represent LRU Cache.
  4. Write a java program to find unique element from array of duplicates. For Example, 

Input Array : 1 2 1 1 2 3 4 2 4 5 2 4 5
Output         : 3
Assume that array size is too large or infinite. You need to write an optimal solution.

Answer : If you are allowed to use external datastrucure, you can use HashMap Approach.

  1. How I will get to know that whether my child thread has completed execution or it has thrown an exception?
  2. Do you know any way to return a value from your child thread to main thread?
  3. What's the difference between Future and FutureTask in Java?
  4. Suppose I have furniture shop. 
  • In furniture shop, there are objects like table, chair, doors
  • Each objects can be made up of material like wood, glass, plastic
  • Each object can have different weight based on the material being used

      Which all classes you will use to represent above furniture shop and design a class diagram for the same.

  1. How Garbage collector works? Tell me about different memory areas in JVM.
  2. You are given a large number of files which contains comma separated data as 'personName,skill' as shown  below

File 1:

File 2: 

File 3:

I want to write a program which will give me following output:


Also mention which datastructure you will use and why?

  1. Why Concurrent HashMap is a good choice for many read operation and less write operations?
  2. Why do you want to join Morgan Stanley?
  3. Why do you want to relocate to Mumbai?
