Weekly Challenges are short, repeatable activities that enable users to apply skills in a focused and time-efficient manner. They complement SkillUp learning paths and certifications by offering ongoing practice rather than long-form coursework.

Weekly Challenges support the following objectives:

• Provide structured opportunities for continued learning after completing badges or certifications

• Encourage consistent participation through a predictable weekly cadence

• Introduce a controlled competitive element within an organization

Accessing weekly challenges

To access the weekly challenge: 

1. Log in to your SkillUp account using your credentials. 

2. Locate the weekly challenge banner on the right side of the homepage.

   

The banner displays the remaining time to attempt the challenge, along with the current and previous week leaderboards.

Leaderboard

Each weekly challenge includes a leaderboard that ranks participants within the same organization.

Leaderboards allow users to:

• Compare their submissions with peers

• Learn from top-performing solutions

• Track progress across multiple challenges

Note: Users can view the previous week’s challenge and winning submissions to learn from them.

Evaluating weekly challenges

Weekly Challenges use token efficiency to evaluate submissions.

Total score = Input tokens (prompt) + Output tokens (generated code)

• Lower scores rank higher

• If scores tie, earlier submissions rank higher

• Each user can submit once per weekly challenge

Available weekly challenges

HackerRank currently offers the Weekly Prompt Engineering Challenge.

Weekly Prompt Engineering challenge

The Weekly Prompt Engineering Challenge helps users improve their ability to write effective prompts for large language models (LLMs).

Prompting is a critical skill in modern development workflows. Developers interact with LLMs, agents, and AI-assisted development tools through prompts. Inefficient prompting increases cost by consuming unnecessary tokens or requiring repeated attempts.

This challenge reinforces the importance of clear, precise prompts for generating efficient and accurate results.
