I am not agreeing on this. Unless you are hiring an expert, most of developers out there earning their lives by coding can not write a simple bubble sort when you give them a console. Not because they don't have the capacity, They will either not remember the algorithm at the moment or haven't had a such situation requires similar approach at their previous work. If you really want to know if he/she knows stuff, ask him a task/question/bug and let him explain how he would solve it. if he is good, he will start telling the approach in different aspects, he would even start writing you a pseudo code to solve it.

The approach taken in the article is not explaining how to HIRE programmers.

It is about how to ELEMINATE them.

To be fair, eliminating a fair portion of candidates (assuming the test does a good job of identifying the ones you wouldn't hire) isn't a bad thing. Time is a valuable resource.

always write tests while programming :) you did not cover the whole task!

// Your code

  if "Time is a valuable resource."
    Don't waste employers' time
  end

// Refactor

// Adds candidates' time to the case

// Decreases listOfCandidates() loading time.

  if "Time is a valuable resource"
    Publish a well-detailed job position
  end
