I am curious how much effort various companies put into the hiring process these days. Does your company just seek to quickly fill open positions with whatever "warm bodies" they can find, or do they put a great deal of time and effort into finding just the right candidate -- preferring to leave a position open longer than they would like if it takes longer to find the right person? Or somewhere in between?
I have seen the "hiring process" lead to outcomes that did not meet expectations. Where I have some measure of control, I have changed my thinking about the 'hiring' as the process;
instead I think of 'hiring' as one step in an 'employment process'. For my direct reports, this means that I have more than just a job description to offer, but also planned tasks with enough specifics that both I and the potential hire are aware of what they will be asked to do. In the post-hire period, I have an (internal, unvocalized) set of metrics that I am using to evaluate the new hire as they are mentored through the tasks. Later, as I have an assessment of their capabilities we'll collaborate on future activities... as allowed by business needs.
When I'm not the direct supervisor, if I am to collaborate with a new hire I will adopt a peer-mentorship approach. Such new hires are under no obligation to pay attention to me, of course! My experience has been that new hires that don't look for peer-partners are more prone to have 'issues' at work which can impact everyone's performance.
