Round 1 (Technical) (1.5 hrs)
This round was focused on Java, DBMS, Problem solving and DSA

• Java Questons: Java 8 features, Anonymous class, String pool, Indexing, Indexing internal working, Sprinboot annotations, Distributed Systems, Locking, etc.
• Shortest path finding between different metro stations on different lines.
• Longest Increasing Subsequence with running code.

Round 2 (Technical) (1.5 hrs)

• Project discussions and tech problem solved
• HLD for Social Media Platform
• Code implementation for Connection Pooling system
  The pool should be configurable with a minimum (min) and maximum (max) number of connections. It should use a provided DataSource (ds) for creating new connections. Core Methods: createConnection(): Uses the DataSource (ds) to create a new connection. getConnection(): Returns an available connection from the pool. If all connections are in use, the method should wait until a connection becomes available. releaseConnection(Connection conn): Allows returning a connection back to the pool. closeAll(): Closes all connections, typically used during a shutdown or cleanup process. Design Considerations: Thread Safety: Ensure the implementation is thread-safe, allowing concurrent access to connections. Maximum Connection Limit: The pool must not exceed the defined maximum number of connections. Efficiency and Patterns: Consider using design patterns for a clean and efficient implementation.
• Technical Questions: Java Questions, Distributed Systems Questions and scenario based questions to implement Java concepts.

Round 3 (Managerial) (2 hrs)
