Project-Based Java Round
After the evaluation of the take-home assignment, candidates progressed to a project-based Java round. This round focused on a deep dive into the implementation and design decisions made in the parking lot management system. Interviewers examined the architecture of the solution, scrutinizing the choice of data structures for efficient parking slot allocation, algorithms employed for vehicle management, and strategies for handling various vehicle types effectively. Moreover, discussions revolved around scalability, extensibility, and potential optimizations aimed at enhancing system performance and robustness.
Technical Round 1:
1. Java Concepts:
– Proficiency in core Java concepts such as object-oriented programming (OOP), inheritance, polymorphism, and exception handling was rigorously evaluated.
– Understanding of advanced Java features like generics, concurrency, and Java 8 features such as streams and lambdas was assessed to gauge the candidate’s depth of knowledge.
2. Spring Framework:
– In-depth knowledge of the Spring framework was examined, with a focus on concepts including dependency injection, inversion of control (IoC), and the usage of Spring Boot for developing scalable and maintainable applications.
3. Database Management:
– Candidates were expected to demonstrate proficiency in database concepts and SQL queries, particularly in the context of integrating databases with Java applications.
– Discussions encompassed database design principles, normalization, indexing strategies, and transaction management.
4. Problem-Solving:
– Analytical thinking and problem-solving abilities were put to the test through discussions on optimizing code, handling edge cases, and improving system performance.
– Candidates were presented with algorithmic challenges and were evaluated on their approach to problem-solving and the efficiency of their solutions.
