These issues are easier to solve at the time they occur while applicants are already engaged. This will also help ensure that applications are complete at time of sourcing close for assessment, rather than having to waste time following up on applicants.
Specifically for us:
Our recruitments have strict public sector governance controls and all feature written submission components. At the end of the recruitment process, applicants have a period where they may lodge a breach of process complaint. By not notifying the parties at the time, this issue wasn't able to be resolved before sourcing closure. This exposes recruiters to a breach of process risk if they accept corrected documents after closure, on grounds of perceived advantage by having additional time to work on written components. This would be mitigated if the parties were informed and the issue resolved while the job is still sourcing.
