The technical rounds mix Java, Spring Boot and SQL questions with behavioral ones, and lean on your past projects.\n\nQuestions in this area, for example:\n\n- **Java**: `HashMap` internals and why `equals` and `hashCode` must agree; checked vs unchecked exceptions; `final`, immutability and thread safety; what `synchronized` actually locks.\n- **Spring Boot**: how dependency injection resolves a bean and what happens with two candidates; `@Transactional` propagation and where it silently does nothing (self-invocation); building a REST controller with validation; JPA lazy vs eager loading and the N+1 problem.\n- **SQL**: write a query returning the top 3 subscribers by monthly usage per plan; explain a plan that ignores your index; difference between `WHERE` and `HAVING`.\n- **Behavioral**: a production issue you owned, and how you handle conflicting priorities from two managers.\n\n## What they look for\n\n- Depth on whatever you claim on your CV; they pick the framework you list and go three questions deep.\n- Practical answers (\"I would check the transaction boundary first\") over definitions.\n- Reasonable SQL fluency without an IDE; they may hand you a pen.",
    "follow_ups_md": "- How would you cache a slow read endpoint in Spring and invalidate it safely?\n- Where would you put a rate limit for a public API in a telecom stack?"
