README

This assessment helps us gauge your ability to code, work in an existing codebase, and follow guidelines. It's estimated that this assessment will take about two hours to complete.

Setup

Before you can start you'll need to setup the project.

These instructions are generalized, and written on a Mac. You'll need to adapt as necessary if you are working on a different platform.

Also, make sure you kill any running packagers for other React Native apps before starting

Dependencies

• node.js
• yarn
• React Native

Quick Steps

# Install project dependencies
$ yarn

# Start the React Native Package Manager
$ yarn start

# Run the mock HTTP server
$ yarn run mock-server

# Start up the application in an iOS simulator
$ react-native run-ios

# To run the test suite for Problem 4:
$ yarn test

Rules

• You cannot add any dependencies or packages.
• You cannot modify any code outside of the ./app and ./test directory.
• You can modify/add/remove code in ./app/components and ./app/containers.
• You cannot add any files in ./app/reducers or its subdirectories.
• You can only modify the following files in ./app/reducers and its subdirectories:
  • ./app/reducers/applicant/applicantSelectors.js
  • ./app/reducers/skill/skillSelectors.js
• You can only modify the following files in ./test/reducers and its subdirectories:
  • ./test/reducers/applicant/applicantSelectors.spec.js
  • ./test/reducers/skill/skillSelectors.spec.js

REMEMBER: We want to see how well you can work in an existing code base.

Problem Set

See examples/before.png.

1. Fix the implementation of getApplicantsWithSkills in ./app/reducers/applicant/applicantSelectors.js

Currently the implementation returns a list of applicants with an empty set of skills.

However most applicants have skills associated with them.

If done correctly, this will make the next two problems much simpler

DIFFICULT: Easy

EXAMPLE: ./examples/problem-1.png

2. Display each applicants' top skill in the list of applicants.

We consider an applicant's top skill to be the skill with the most years of experience.

For example if Bob has 3 years of experience with PHP, and 5 years of experience with Objective-C, then Bob's top skill is Objective-C.

If the user has no skills, then you can show nothing.

If the user has multiple top skills you can show whichever skill you like.

HINT: See ./app/components/applicants/ApplicantRow.js

DIFFICULTY: Easy

EXAMPLE: ./examples/problem-2.png

3. Change the sort order of applicants' when the sortOrder value changes.

Based on the sort order in the redux state, the applicants should be sorted by their total count of skills.

HINT: There is a stub function in applicantSelectors.js which, if implemented correctly, will be all you need to do.

DIFFICULTY: Medium

EXAMPLE: ./examples/problem-3-sorted-asc.png EXAMPLE: ./examples/problem-3-sorted-desc.png

4. Update the tests to test any functionality added to ./app/reducers.

We test all functionality that is found in the reducers or lib folders, so we need to extend the code coverage there to test what you have added.

HINT: Only worry about finishing the test for applicantSelectors.getApplicantsWithSkills and adding tests for any other methods you chose to add to applicantSelectors, and all methods you added to skillSelectors.js

HINT: Our test suite currently runs on Jest

HINT: running yarn test in the command line will start Jest

DIFFICULTY: Medium

Your Notes

If you have any notes with regards to your solution, leave them below this line.

If you feel the test is unreasonable, please explain your reasoning so we can make the test better by emailing [email protected] or [email protected].
