Java 21 Advanced Concepts/Interview Preparation

Master Java 21 with a deep dive into advanced language features and real-world interview scenarios. This service is designed for experienced Java developers who want to strengthen their core fundamentals while gaining clarity on modern Java evolution used in production systems today.

The sessions cover Java 21 enhancements, JVM internals, memory management, garbage collectors, concurrency and multithreading, virtual threads, structured concurrency, immutability, performance tuning, and low-level design patterns. Each concept is explained through practical examples, edge cases, and common interview traps asked by top product and service-based companies.

You will also work through high-quality interview problems, system-level questions, and coding scenarios with a focus on how to think, explain, and optimize solutions. Special emphasis is given to writing clean, readable, and performant code, along with tips on articulating design decisions confidently during interviews.

This service is ideal for mid to senior Java developers preparing for product companies, architect roles, or leadership positions, who want structured preparation, conceptual depth, and real-world confidence rather than surface-level revision.
