About Java-success.com

This online training was developed based on the book Java/JEE Job Interview Companion that was first published in 2007, and sold around 35,000+ copies via amazon.com.

The book is outdated, and replaced with this industrial strength membership (i.e. 1700+ members) site to learn on the go.

Experienced professionals…

Ask the right questions: Is my code thread safe? Is my project CI/CD ready? Should I containerise it with Docker? Am I dealing with Big Data here? Should I go for batch processing or real-time streaming? Can I achieve low latency here via MPP? Do I have enough unit test coverage? How can I partition the data to reduce shuffling and data skew? How can I debug memory leaks? How can I promote loose coupling here? and so on…….

Why wait years to gain experience when you can proactively learn & apply a lot sooner.

Why Q&As approach?

If you are an employer it pays to hire well rounded candidates by asking the right questions.

If you are an employee it empowers you to take your know-hows & skills to the next level.

Q&As approach to learning is not only thought provoking, but also more concise and quicker to learn a wide range of key concepts than reading 50+ books with hundreds of pages. You always have Google.com & Youtube.com to drill down if you know what questions to ask.
