Easily Hire The Right Java Developers

2. Skill Validation

This assessment tests the candidate's knowledge of Java fundamentals. It comprises a series of engaging challenges designed to evaluate candidates' theoretical and practical proficiency in Java. Each challenge focuses on a subject area and includes Q&A sections covering concepts, features, and real-world situations.

A technologist is approved in this test if all challenge level cut-off scores at met.

Java Fundamentals

Tests candidate familiarity with Java concepts and features. Questions range from very easy to fairly difficult, so the score should let you differentiate between both junior and senior developers as well as between seniors.

SCM & Git

Evaluates the candidate's knowledge and familiarity with git with a focus on the command line application.

Design Patterns & System Design

Checks candidate's familiarity with design patterns and system design principles.This challenge contains conceptual and practical questions about design patterns and SOLID principles.

Microservices Architecture

This challenge tests the candidate's knowledge of microservice and SOAP web services architectures. It covers REST vs. SOAP, Microservice architecture and distributed services communication.

Java Code Challenge

Tests a developer's ability to understand requirements and implement a system that matches them. This is an intermediate-level problem, comprising the implementation of a state-machine class. No specific framework is required for this challenge.

3. Technical Interview

This assessment evaluates the candidate's expertise in Java through a real-time coding challenge. It's designed to be used as an interactive session with the technical screener.

During the assessment, candidates will tackle a hands-on problem tailored to the core principles of Java. Their solution will be frist verified by a battery of automated test cases to ensure it meets the functional requirements as well as industry standards. Then, our experienced interviewers step in to assess the overall efficiency of the candidate's solution.

Assessment Outline:

• Java Coding Challenge (Option 1):
  • This is an intermediate-to-advanced-level problem, comprising a parser class implementation. No specific framework is required for this challenge.
• Java Coding Challenge (Option 2):
  • This is an senior-level assessment used for interviews for more specialized roles, focused on coding skills. It's composed of two different challenges:
    • Spring Boot debug: This challenge helps validate that candidates can quickly get up to speed with a Spring codebase and apply a bug fix. The challenge is designed such that candidates who are familiar with Spring Boot should be able to solve it in short order, while candidates unfamiliar with Spring Boot either won't be able to solve it at all, or will only be able to solve it with extensive research and time.
    • Java Streams API: This challenge is designed to test the candidate's ability to use the Streams API by extending the functionality with a custom generator implementation.
