At TriStarr, we have long believed and preached that the more objective your selection process the greater your chances are of making a good hire. If your hiring process is composed of simply reviewing resumes and interviewing candidates, your statistical chances of making a good long term hire are basically 50/50 – a coin flip (email me for an excellent graphic that illustrates these odds). By adding relative hard skills tests, personality assessments, work examples, and other tools you can significantly increase those odds.
Here’s a link to an article that was forwarded to me recently that speaks to this issue. I hope you find this useful -and as always if you have any questions, please don’t hesitate to ask.
