Time2Fill — vacancy fill forecasting

The problem

Open vacancies need a forecast that can be revised as the process unfolds — not a one-shot estimate at posting time. The questions are whether a vacancy is likely to fill within a useful horizon, and how much remaining time should still be expected.

Approach

Time-to-fill is modelled as accelerated failure time. Vacancies still open at the cut-off are treated as censored. Daily process information enters as time-varying covariates; applications are covariates only.

Outcome

A daily read on the open book: which vacancies look likely to fill soon, and which look stalled.
