• Advanced concepts (less common) – Backpressure management, custom codec implementation for the event bus, and integrating legacy blocking APIs using worker verticles.

Example questions or scenarios:

• "Write a Vert.x handler that fetches data from an external API asynchronously, processes it, and saves it to a database without blocking the event loop."
• "How would you diagnose and resolve a 'blocked thread' warning in a production Vert.x application?"

Database Schema & Query Optimization

Data persistence is at the core of any backend platform. You must show that you can design efficient schemas and write queries that perform well under heavy loads.

Be ready to go over:

• SQL Schema Design – Normalization, indexing strategies, foreign keys, and designing schemas for complex transactional systems.
• NoSQL Integration – When to use document or key-value stores, document modeling, and handling eventual consistency.
• Query Performance Tuning – Analyzing execution plans, identifying bottlenecks, and optimizing slow-running queries.
• Advanced concepts (less common) – Database sharding, read-replicas synchronization, and implementing distributed locking mechanisms.

Example questions or scenarios:

• "Design a database schema for a real-time messaging application that supports millions of active users and instant message retrieval."
• "Given a slow-running SQL query with multiple joins, walk me through how you would use an execution plan to identify and fix the bottleneck."

Modern CI/CD & Containerization

A strong platform engineer ensures that code moves from development to production seamlessly, securely, and reliably. You will be tested on your practical DevOps knowledge.
