Recruitment Graph Model

Professionals from the recruiting industry deal with highly interconnected data every day. Making sense of data from various sources in order to match the best candidate for the job is challenging. Companies are now more specific in terms of job profiles and requirements and candidates are more choosy about their roles and responsibilities.

Graphs are a perfect way to model this data. An extremely simple model is depicted in this GraphGist but one can see how it could be extended very naturally to include a much larger variety of data.

This sample dataset includes the following:

Persons and the county they reside in
Their jobs,roles and companies
Competencies, skills and certifications
Ratings (employees rating companies and managers rating employees)
