The 7 Pillars of Zero Trust Security: A Developer's Zero Trust Christmas Carol

Conducting technical tests is a common practice in the hiring process for junior programmers. These tests help assess candidates’ coding skills, problem-solving abilities, and familiarity with programming concepts. Here are ten technical tests suitable for evaluating junior programmers:

1. Algorithmic Problem Solving:

   • Objective: Assess problem-solving skills and algorithmic thinking.
   • Test: Provide a coding challenge that requires candidates to solve a specific problem using algorithms. This could involve tasks like sorting, searching, or dynamic programming.

2. Basic Data Structures:

   • Objective: Evaluate understanding of fundamental data structures.
   • Test: Ask candidates to implement or manipulate basic data structures like arrays, linked lists, or stacks. This helps assess their understanding of how to use and manipulate these structures.

3. String Manipulation:

   • Objective: Test proficiency in handling strings.
   • Test: Present tasks that involve string manipulation, such as reversing a string, finding substrings, or checking for palindromes.

4. Database Fundamentals:

   • Objective: Assess knowledge of database concepts.
   • Test: Pose questions or tasks related to basic SQL queries, database design principles, or understanding of relational databases.

5. Debugging Skills:

   • Objective: Evaluate the ability to identify and fix code issues.
   • Test: Provide code snippets with bugs and ask candidates to debug and correct the issues. This assesses their troubleshooting and code review skills.

6. Web Development Basics:

   • Objective: Test understanding of web development concepts.
   • Test: Pose questions or tasks related to HTML, CSS, and basic JavaScript. This could include tasks like creating a simple webpage or solving CSS layout problems.

7. Version Control (Git):

   • Objective: Assess familiarity with version control systems.
   • Test: Ask candidates to perform basic Git operations, such as creating branches, making commits, or resolving merge conflicts.

8. Code Review:

   • Objective: Evaluate code quality and adherence to best practices.
   • Test: Provide a piece of code and ask candidates to review it for potential improvements, identifying issues, and suggesting enhancements.

9. Problem-Solving with APIs:

   • Objective: Test ability to work with external APIs.
   • Test: Ask candidates to integrate with a public API, perform basic operations, and handle responses. This assesses their understanding of HTTP requests and API communication.

10. Understanding of Frameworks:

    • Objective: Assess knowledge of popular frameworks.
    • Test: If your organization uses a specific framework, ask candidates to complete a task or solve a problem using that framework. This could involve tasks in frameworks like React, Angular, or Django.

When designing technical tests, it’s essential to balance complexity and relevance to the role. Additionally, providing candidates with a realistic development environment or tools they are familiar with can contribute to a fair evaluation.
