Managing configuration across multiple microservices sounds simple—until you need to update values across different environments while maintaining consistency and control.

A few questions worth considering:

• Where should configuration truly live in a distributed system?
• How do teams avoid configuration drift across environments?
• What’s the best way to manage configuration changes without touching every service?
• How can microservices maintain a single source of truth for configuration?

These are common challenges in modern microservice architectures and frequent discussion points in senior Java and system design interviews.

I’ve shared a quick 2-minute overview covering one of the most widely adopted approaches to solving this problem in the Spring ecosystem.

🗒️ Java Interview Experince (10+ YOE)

Recently documented my interview experience with Marriott International Tech Accelerator for a senior Java/backend engineering role (10+ years experience).

The discussions were focused on practical backend engineering concepts including:

- Cache design concepts
- API security and rate limiting
- Microservices architecture
- Scalable system design

What stood out was the emphasis on production-level thinking, clean design approaches, and real-world problem solving rather than theoretical answers.

I’ve summarized the overall experience, architecture discussions, and key learnings in the article below:

I’ll continue sharing more interview experiences and backend engineering discussions from the interviews I attended recently.

⚡ Parallel Streams in Java look easy… But MOST developers use them WRONG.

💡 Quick insights:

• Uses ForkJoinPool under the hood
• Not always faster (depends on task type)
• Stateless = safe ✅
• Shared data = bugs ❌

🔥 One mistake → performance drop or weird concurrency issues

I’ve broken this down in a 90-sec video — perfect for interviews & real-world use:

Recently went through a series of interviews for senior Java positions and documented one of the interview experience at EPAM.

The discussions were heavily centered around applying core concepts in real scenarios

— especially Java 8, concurrency, and microservices architecture
— rather than surface-level knowledge.

Sharing this as a reference point for anyone preparing at the 10+ years level 👇

CompletableFuture vs Traditional Multithreading :

👉 Understanding the difference between Future and CompletableFuture in Java is not just an interview topic, it directly impacts how we design scalable and responsive backend systems.

👉 While Future is limited and blocking, CompletableFuture enables non-blocking ex*****on, chaining, and better handling of parallel tasks.

👉 In modern microservices and API-driven systems, this shift is critical for performance and user experience.
