The handoff where hiring data goes to die
Recruiting software stops holding data at the offer letter. HR software starts at the start date. The most useful question in hiring sits in the gap.
Ask most companies whether the people they hired last year worked out, and the honest answer is that nobody can compute it. Not because the data does not exist, but because it is in two systems that were never joined.
The applicant tracking system knows who applied, what they scored and who interviewed them. The HR system knows who is still employed eighteen months later. The join between them is a spreadsheet somebody made once, which was wrong within a month of being made.
We built the join into the product instead. Moving a candidate to Hired creates their employment record carrying the application and the job that produced it. Nothing is retyped and nothing is exported. That is what makes 'did our high scorers become good employees' a query rather than a project.
It is also why we did not build only an ATS. Half the chain answers none of the question.
