​A pet wiki wants to add Selenium tests for their website. One thing common to many pages that they want to test is dynamic loading of data, and they want to test if it's fast enough.

Finish the getLoadedData method that accepts a WebDriver instance that has the desired page loaded. The method should click the button with the id "load-button" and wait up to 1 second for the button to become enabled again. If the button gets re-enabled in 1 second, the method should return the content of the paragraph with the id "content" as soon as possible. Otherwise, the method should return null.

For example, if getLoadedData is called with a WebDriver instance with the following page loaded, provided here and below:

<!DOCTYPE html>
      function loadData() {
        document.getElementById("load-button").disabled = true;
        setTimeout(() => {
          document.getElementById("content").innerHTML = "The Maltese is a breed of dog in the toy group.";
          document.getElementById("load-button").disabled = false;
        }, 500);
    <p id="content" >
      The Maltese....
    <button id="load-button" onclick="loadData()">
      Click here to load additional data.

the method should return "The Maltese is a breed of dog in the toy group.".

  •   Example case: Wrong answer
  •   The method returns the correct String if the button gets re-enabled: Wrong answer
  •   The method returns the correct String if the button gets re-enabled, or null if it doesn't: Wrong answer
  •   The method returns the correct String as soon as the button gets re-enabled: Wrong answer

Screening Applicants: The Good, the Bad and the Ugly

Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?

Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
