Zenjob Coding Challenge

This is a backend coding challenge, containing three different tasks. The repository consists of a simplified version of Zenjob's platform:

• Companies can order jobs
• Each job contains one or more shifts
• Talents (workers) can be booked for shifts

No bootstrapping needed

To allow you to dive right into it, there is a simplified version of a job service provided, which already contains the following features:

• Creating a job with multiple shifts
• Fetching the shifts for a specific job
• Booking a talent to a shift

Feel free to adjust it as much as you like.

Product boundary conditions

There are certain boundary conditions defined which must be met by the service.

• A job should have at least one shift
• The start date of a job cannot be in the past
• The end date of a job should be after the start date
• A shift's length should equal to 8 hours

Out of scope

In order to keep the scope reasonably sized, there is no possibility for a company to request jobs for specific times.

Objective

Your job is to modify the existing service so it satisfies the following requirements:

Task A

• AS a company
• I CAN cancel a job I ordered previously
• AND if the job gets cancelled all of its shifts get cancelled as well

Task B

• AS a company
• I CAN cancel a single shift of a job I ordered previously

Task C

• AS a company
• I CAN cancel all of my shifts which were booked for a specific talent
• AND replacement shifts are created with the same dates

Evaluation criteria

Your submission will be evaluated by at least 2 people on the following criteria:

• Completeness
• API design
• Tests
• Solution design
• Code styling
