Digital personnel file & data model
HiBob
Marketing names a 'Core HR system of record' with eSign and document management, but the evidence evidences no org structure, no custom fields, and no dated history — I cannot confirm it keeps contract or salary history rather than overwriting it. The API and data-model documentation that would let me build identity on top of it are entirely absent from the evidence.

The captured pages confirm a human capital management product holding demographic, tax and compensation data with audit trails in the background, but we found no public information on a digital personnel file, document storage, an org chart, custom fields, or effective-dated history of contract and salary changes. Since I want the HR system to be the source of truth for accounts, it also matters that we found no public information on an API or provisioning surface for this data. That leaves records somewhere between a flat store and a real personnel file.
