Interview Preparation Tips

Interview preparation tips for other job seekers - If you have declined JPMC's offer in last 2 years. You would be in cooling off period. I had declined their offer last year for genuine personal reason and not on the last min.
So when I cracked all round with amazing feedbacks and even after compensation discussions happened. After 2 months long process, I was told that they can't role out my offer letter because I am in that 2 years cooling period!!
The central hiring process of the company should not allow applicant to apply if such policies are in place. How would an applicant know that they are in cooling period? The policies are for HRs and recruiters to know. But sadly none of them were aware and ended up wasting my 2 months!! Very disappointed!

This round focused more on Multithreading concepts from Java and also some core concepts from OOPS.

  • Q1. What is a thread in Java?
  • Ans. 

    A thread in Java is a lightweight sub-process that allows concurrent execution within a single process.

    • Threads allow multiple tasks to be executed concurrently in a Java program.

    • Each thread has its own stack and program counter, but share the same memory space.

    • Threads can be created by extending the Thread class or implementing the Runnable interface.

    • Example: Thread t1 = new Thread(new MyRunnable()); t1.start();

  • Answered by AI
  • Q2. What are the start() and run() methods of the Thread class in Java?
  • Ans. 

    The start() method is used to start a new thread, while the run() method contains the code that will be executed by the thread.

    • start() method is used to start a new thread and calls the run() method internally

    • run() method contains the code that will be executed by the thread

    • It is recommended to override the run() method with the desired functionality

  • Q3. What is the difference between the Thread class and the Runnable interface when creating a thread in Java?
  • Ans.

    • A class can only extend one abstract class, but can implement multiple interfaces.

    • Abstract classes are used to define common behavior among subclasses, while interfaces are used to define a contract for cla...

  • Q5. What is the garbage collector in Java?
  • Ans. 

    Garbage collector in Java is a built-in mechanism that automatically manages memory by reclaiming unused objects.
