• Relational Databases & SQL – Writing complex joins, subqueries, indexing, and understanding transactions.
• API Design & Integration – Building and consuming RESTful web services, handling JSON/XML payloads, and managing authentication protocols.
• Advanced concepts (less common) – Microservices communication patterns, database partitioning, and caching mechanisms like Redis.

Example scenarios:

• Explaining the difference between WCF and Web API, or describing how @Autowired handles dependency injection in Spring.
• Writing a SQL query using joins and aggregate functions to retrieve specific analytical data from multiple relational tables.

Embedded Systems & Protocol Engineering (Specialized)

If you are interviewing for roles within embedded software, automotive electronics, or hardware testing, the evaluation shifts toward low-level programming and hardware communication.

Be ready to go over:

• C/C++ and Embedded Systems – Pointer arithmetic, memory mapping, interrupt handling, and real-time operating systems (RTOS).
• Communication Protocols – Deep familiarity with protocols like UART, I2C, SPI, or CAN.
