Frequently Asked Questions

How to prepare for a senior Java interview?

Senior Java positions require a detailed and clear understanding of concurrency. Knowledge of concurrency and multithreading, in addition to Java fundamentals, design patterns, system architectures, and JVM internals, can place interviewees at a considerable advantage.

Which method is best for multithreading in Java?

In Java, the best method for multithreading largely depends on the use case, but implementing the runnable interface is often considered a preferred alternative approach over extending the Thread class.

Is multithreading important for an interview?

Multithreading is a core concept often discussed in interviews for roles related to software engineering, systems programming, and performance-critical applications. A multitasking programming technique allows various threads to run simultaneously within a single program. If you are interviewing for a developer role, you will most likely be asked to explain multithreading and its importance in programming.
