In this video, I am sharing a *real Persistent Systems Java Developer interview experience* for around **2 years of experience**.

Sai Kiran had around 1.9 years of experience and was trying to switch his company. Initially, he was struggling to get interview calls and was also finding it difficult to explain his answers confidently.

After attending a free mock interview, working on the feedback, and improving his technical knowledge and communication, he attended an interview with *Persistent Systems* and successfully cleared it with a package of around **9 LPA**.

In this video, I have covered *30 real interview questions* from topics including:

✅ Core Java
✅ Spring Boot
✅ Java Multithreading
✅ Collections
✅ Hibernate & Spring Data JPA
✅ Database & Connection Pooling
✅ Microservices
✅ Saga Pattern
✅ Kafka
✅ REST API & Idempotency
✅ API Rate Limiting
✅ Service Discovery
✅ Inter-Service Communication
✅ Deployment concepts

I have explained every question in *simple and interview-ready language* so that you can understand not only what to answer, but also how to explain your answer confidently during an interview.

If you are preparing for Java Developer interviews with **2–5 years of experience**, make sure you watch the complete video.
