In this video, I share my real interview experience at TCS for a Java Backend Developer role.
The interview focused on Core Java, Java Streams, Spring Boot, Microservices, Collections, SQL, and real production scenarios.

Topics covered in this interview include:
Java Streams API and real project usage
ConcurrentHashMap and multithreading concepts
Deadlock prevention and garbage collection
Spring Boot production issue debugging
Microservices deployment across multiple data centers
Spring Security and Spring Batch usage
Collections and SQL scenario-based questions
Design patterns and real-world architecture decisions

The interview was highly scenario-driven, testing practical knowledge, production readiness, and problem-solving skills rather than just theory.

This video will help developers preparing for TCS, Infosys, Mphasis, EPAM, Deloitte, Accenture, and other Java backend roles.
