Concurrency in Java is one of the most complex and advanced topics brought up during senior engineering interviews. Knowledge of concurrency and multithreading can put interviewees at a considerable advantage. This course lays the foundations of advanced concurrency and multithreading and explains concepts such as Monitors and Deferred Callbacks in depth. It also builds simple and complete solutions to popular concurrency problems that can be asked about in interviews like the Reader-Writer Problem and the Dining Philosopher Problem. While prior knowledge of concurrency is not required to follow through with this course, familiarity with the very basics of concurrency would be helpful.

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.
