Let's build a matchmaking system that helps discover jobs for developers based on a number of factors.
One of the simplest, yet most important factors is compensation. As developers we know how much money we need to support our lifestyle, so we generally have a rough idea of the minimum salary we would be satisfied with.
Let's give this a try. We'll create a function match (job_matching in Python) which takes a candidate and a job,
which will return a Boolean indicating whether the job is a valid match for the candidate.
A candidate will have a minimum salary, so it will look like this:
candidate = {
'min_salary': 120000
}
A job will have a maximum salary, so it will look like this:
job = {
'max_salary': 140000
}
If either the candidate's minimum salary or the job's maximum salary is not present, throw an error.
For a valid match, the candidate's minimum salary must be less than or equal to the job's maximum salary. However, let's also include 10% wiggle room (deducted from the candidate's minimum salary) in case the candidate is a rockstar who enjoys programming on Codewars in their spare time. The company offering the job may be able to work something out.
def match(candidate, job)
job['max_salary'] >= candidate['min_salary'] * 0.9
end
