Suppose you set out to build a house using only a hammer.
You probably wouldn't succeed, right?
It's not that hammers are bad.
There's just a limit to what hammers can do.
To build a house right, you need a variety of tools in your toolkit:
3) Tape Measure
4) Electric Saw
To hire right, your situation is no different.
Many different hiring methods exist:
2) Structured interviews
3) Work Samples
4) Reference Calls
Like the hammer, no one hiring method is perfect.
Each method has its unique strengths and weaknesses.
So if you're going to build a hiring process that's accurate, you're going to need the entire toolkit that's available to you.
That way you mitigate the weaknesses of each hiring method, while leveraging their combined strengths.
You wouldn't build your house with just a hammer.
Don't make the same mistake in your hiring process.
