5. Company Culture
When hiring a new employee, the personal fit for the company as a whole should come into play as well.
You may be hiring someone that has impeccable office manager skills, but unless they fit with the company culture or team as a whole, conflicts or poor performance will eventually manifest.
This could lead to more turnover or a generally unhappy environment. Rather than stalled projects or office tension, the right fit will aid in general business productivity.
Using a skill test can help bypass the shaky foundation that comes from hiring someone who may not fit in with a divergent personality or skill set.
