Round 1 - Technical 

(2 Questions)

  • Q1. Does Java support pass by reference?
  • Ans. 

    Yes

    • Java uses pass by value for all variables, including object references.

    • When an object reference is passed as an argument, a copy of the reference is passed, not the actual object.

    • Modifying the reference inside the method will not affect the original reference outside the method.

    • However, modifications to the object's state inside the method will be visible outside the method.

  • Answered by AI
  • Q2. Explain Singleton Pattern
  • Ans. 

    Singleton pattern restricts the instantiation of a class to a single object.

    • Singleton pattern ensures that only one instance of a class exists throughout the application.

    • It provides a global point of access to the instance.

    • Commonly used in scenarios where a single instance needs to coordinate actions across the system.

    • Example: Database connection manager, logger, configuration manager.

Interview Preparation Tips

Interview preparation tips for other job seekers - Please confirm before appearing your expected CTC , Management is not good , It is product based but pay scale is very less . I cleared all round & in HR round my current CTC was compared to expected one , even I was holding good offer in hand . After that I haven't received any communication from them yes or no nothing. Giving salary like service based company and less number of people in technical team will only lead to work pressure without pay .
