How can I tell if someone is competent in programming?

>a good programmer leaves comments on his code

Not necessarily true because if your code is self explanatory (method/function names are by themselves descriptive enough of what it does) then there is no reason to add comments.

 

I.e. don't do this:

-- Multiplies the number by two
function multiplyByTwo (let number)
{ 
  number = number*2; 
console.log(number)
}

 

Agreed. Most Apache projects are perfect examples of great programming that are poorly documented.

Normally you have to be competent to know it, making a test or watching at hers code helps

As the title states, I was wondering if there was a way to find out if people truly know how to code before hiring them.

 

Thanks! All help is appreciated.
