In my experience, the hiring managers with the best track record have these in common, which mostly boil down to the hiring teams doing their homework:
(1) The expectations for the position are clearly defined
(2) The hiring team members coordinate on questions and expected responses, and they are consistent in interviews.
(3) The hiring team members know how to spot potential issues (e.g., excessive bad-mouthing of previous employers, etc.)
(4) The hiring teams effectively leverage their networks for references. Ideally, there are not-too-distant trusted relationships between the candidate and the hiring team. In the absence of this, references are followed up on carefully (this has become an art form in modern times.)
These reduce the risk of someone slipping through the cracks. Hiring teams also get better with experience, so any mistakes should be carefully analyzed and corrective actions incorporated into the hiring process.
