How do you create a baseline standard across your team for how to conduct interviews?
We have done some research into the actual interview techniques (#, #, #, #, #). What I'm looking for is to see how others have inculcated these habits into the entire team, so that the recruiting process is consistent and effective.
Background: A big pain point of my IT team's interview process is that there are no standards. One developer may conduct a 30-minute informal interview, while another may do hour-long deep dives into their favorite technology. So far we've done okay because we have recruited through personal referrals... but we're now growing and interviewing unknown candidates a lot. Some bad apples were hired, that has led to introspection on our part. We don't want to stifle our developers' interview styles by "mandating" a standard set of questions, but we do want a consistent level of rigor and a consistent evaluation method.
