Historically, a single candidate could only respond once to the same position. However, there are cases where such "duplication" is desirable (e.g., for long-term open positions, the same candidate may apply again a year later) or the absence of such an option causes problems (e.g., an automatic response to the candidate is not sent if the "duplicate" response is not allowed).
In addition to measuring SLA directly on the ATS Recruitis homepage, you can have a report generated via email.
When rejecting a candidate, you can record the reason for rejection, which is automatically reflected in your statistics and reports, and also serves as a tool for searching candidates in the database. This allows the reasons to be best tailored to your needs.
