As a recruiter, I want to upload candidates' information from an API (CRM, ATS) including additional files so that the system can process and rank candidates based on their qualifications.

* The system should support API integrations for uploading candidate information from CRM, ATS, and other systems.

* Each uploaded candidate should be assigned a unique identifier.

* Uploading candidate information via API should trigger the candidate ranking processing back-end engine.

* The system should process the uploaded information and rank the candidates.

* After processing, the system should provide two outputs:

** A candidate ranking table, considering all processed candidates.

** A candidate breakdown, showing detailed information per candidate
