Container Diagram (C2)

The container diagram offers an overview of the containers of the system and how they interact with each other.

Container Diagram

According to the service-based architecture ADR-002 we share the database between different containers to improve the simplicity and testability ADR-014. For the matches we use an event-based topic ADR-016.

Important: The AI models will operate as external services, as outlined in ADR-007, to enhance the system's adaptability and testability. These models will serve various purposes, including:

  • Autofilling company information for employers,
  • Generating resume tips for job candidates,
  • Generating S.M.A.R.T stories
  • Developing features for the matching algorithm.

Story Container

  • Anonymize Resume: Removes all personally identifiable information (PII) from the job candidate's resume.
  • Generate S.M.A.R.T Stories: Creates S.M.A.R.T (Specific, Measurable, Achievable, Relevant, Time-bound) stories from the anonymized resume.

This service is implemented as a separate microservice, as described in ADR-009.

Matching Container

  • Feature Extraction: Generates quantitative, human-readable features (referred to as "spiders") from open roles and S.M.A.R.T stories (ADR-010).
  • Match Scoring: Creates a match with a score between open roles and S.M.A.R.T stories using these features (ADR-011).

HR Integration

  • Asynchronous Decoupling: Integrates with external HR systems by asynchronously consuming the matches topic to enable interoperability.
  • Resume Upload: Uploads a resume to the employer's HR system when a match is unlocked.

Since the interoperability with multiple HR systems is a main challenge of this system a C3 HR Integration Components was created.

Analytics

  • Data Gathering: Read-only access to databases and topics, as described in ADR-019, for:
    • Match statuses (unlocked, passed, hired)
    • Survey results
    • Demographic data of job candidates
  • Data Analysis: Detects potential biases in the hiring process.
  • Report Generation: Creates reports for employers and job candidates.

For more details, see ADR-017.
