Round 2: Group Discussion

Duration: 45minutes

Topic: Is work-life balance just a myth?

Round 3: Technical Interview

Duration: 30minutes

Questions asked:

1. Tell me about yourself.

2. Rate yourself in programming languages.

3. What is AI (Artificial Intelligence)?

4. Explain briefly your project.

5. What is a Time-sharing system?

In a Time-sharing system, the CPU executes multiple jobs by switching among them, also known as multitasking. This process happens so fast that users can interact with each program while it is running.

6. Is Java 100% object-oriented?

No, because Java provides support for primitive data types which are not objects.

7. How does a linear data structure differ from a non-linear data structure?

If the elements of a data structure form a sequence or a linear list then it is called a linear data structure. On the other hand, non-linear data structures are those in which the traversal of nodes is done in a non-linear way. Arrays, linked lists, stacks, and queues are examples of linear data structures, while graphs and trees are those of non-linear data structures.

8. What is a queue?

A queue is a data structure that can simulate a list or stream of data. In this structure, new elements are inserted at one end, and existing elements are removed from the other end.

9. What is the use of ‘finalize’?

Finalize is a method used to free up unmanaged resources and cleanup before Garbage Collection(GC). It performs memory management tasks.

After clearing this round, I was invited for the last and the final round.

1. Introduce yourself.
