How to assess Java skills on WeCP?

Java is used for developing a wide range of applications, including web, mobile, and desktop applications, as well as embedded systems and big data processing systems. It is a popular choice for developing enterprise applications because of its scalability, security, and performance.

Java is known for its "write once, run anywhere" capability, which means that programs written in Java can run on any device that has a Java Virtual Machine (JVM) installed.

To accurately assess Java skills, there are several methods that you can use. One option is to ask the candidate to complete a coding challenge or technical assignment that requires the use of Java. This could involve writing code to solve a problem or implement a specific feature. Another option is to conduct a technical interview, during which you can ask the candidate questions about their experience with Java, such as their familiarity with different Java libraries and frameworks, their ability to debug code, and their understanding of object-oriented programming principles. You could also ask the candidate to walk through the code they have written in the past, or to explain how they would approach a specific programming task. Finally, you could consider asking for references from past supervisors or colleagues who have worked with the candidate and can speak to their Java skills.

• Entry-level:
  • Basic syntax and concepts (e.g. variables, loops, conditionals)
  • Object-oriented programming (e.g. classes, inheritance, polymorphism)
  • Exception handling
  • Basic data structures (e.g. arrays, lists, maps)
• Mid-level:
  • Advanced data structures (e.g. trees, graphs)
  • Algorithmic complexity and performance optimization
  • Concurrent programming (e.g. threads, locks, synchronization)
  • Design patterns
• Senior-level:
  • Advanced topics in object-oriented programming (e.g. design principles, SOLID principles)
  • Java 8+ features (e.g. lambdas, streams)
  • Java EE (Enterprise Edition) and web development (e.g. servlets, JSP, JSF)
  • Java frameworks (e.g. Hibernate, Spring)
