WorkCompass Live Coding Challenge

Introduction

This snippet offers a quick glimpse of the WorkCompass Web Application, allowing candidates to explore the system and practice before their live coding interview.

Interview Requirements

Our Live Coding interviews are conducted using VS Code and the Live Share Extension.

You can access VS Code directly in any browser or install it on your operating system.

During the interview, the host will start a Live Share session and provide you with a link to join. If you're using VS Code on your local machine, please ensure the Live Share Extension is installed in advance.

Business Requirements

A manager and an employee collaboratively create a Performance Plan (referred to as a Plan), which outlines key criteria for evaluating the employee’s performance and supporting their professional growth within the company.

Each Plan consists of multiple key criteria (referred to as Item), with both the manager and the employee contributing descriptions. The manager is responsible for assigning ratings to these Items. The employee’s overall performance rating (also referred to as the Subject or Reviewee rating) is calculated as the average of all Item ratings within the Plan.

Technical Requirements

Item

• Every item must be associated with a plan.
• If a plan is deleted, all associated items must also be removed.
• Each item must have a valid positive numerical score (cannot be nil, negative or a String).
• Each item must include a valid description (cannot be nil or empty).

Plan

• Every plan must have a valid due date.

Exercise Requirements

Exercise 1: Calculate Plan Score

The Plan#score must always return its average score based on the items linked to the plan. Formula: Plan Score = Sum(Item Score) / Total of Items

Exercise 2: Show Plan Status

Implement logic to display the plan status:

• If due_date is earlier than today, the status should be "archived".
• If due_date is later than today, the status should be "current".

Exercise 3: User Plan Statistics

Implement the logic in User#performances that returns a hash containing statistics for each user who has at least one plan. The hash should have user name as keys, and each value should be a hash with the following keys:

• average_score: The average score of the user's plans.
• plan_count: The total number of plans associated with the user.

Exercise 4: Find Plans Due Within a Specified Number of Days

Implement the logic in Plan#due_in that returns an array of plans whose due_date is within the specified number of days from today's date. The number of days should be passed as a parameter to the due_in method.

Testing

To verify that all requirements have been implemented correctly, you should be able to execute the RSpec tests without failures:

RAILS_ENV=test bundle exec rspec

Devcontainer

You can build the container in VSCode by pressing CTRL+SHIFT+P and selecting Dev Containers: Reopen in Container. The initial build may take some time, as it needs to fetch and prepare the container.
