jQuery: Make second function wait to execute, until first function is complete

Question

I'm trying to use when and done to make the second function run only after the first one is executed, but it's not working. What I'm trying to achieve here is:

First I use $("#jobshome").load("jobs/newest-jobs .js-toprow"); to load a div from an external page (In the same domain, no cross domain here), then after it is fully loaded, the next script, which is a simple text slider, will run. But now the external HTML isn't loading inside the "#jobshome" anymore.

The result that I get when I don't use this approach is that the whole external div will load inside a single slider, and that's not what I need.

If I use the initial part like this it works, but not as expected:

$(function(){$("#jobshome").load("jobs/newest-jobs .js-toprow");});
        $(function(){

    //rotation speed and timer

My code is as follows:

jQuery(document).ready(function($) {

  $.when(function() {
    $("#jobshome").load("jobs/newest-jobs .js-toprow");
  }).done(function() {

    //rotation speed and timer
    var speed = 3000;
    var run = setInterval(rotate, speed);
    var slides = $('.js-toprow');
    var container = $('#jobshome');
    var elm = container.find(':first-child').prop("tagName");
    var item_height = container.height();
    var previous = 'prevabc'; //id of previous button
    var next = 'nextabc'; //id of next button
    slides.height(item_height); //set the slides to the correct pixel height
    container.parent().height(item_height);
    container.height(slides.length * item_height); //set the slides container to the correct total height
    container.find(elm + ':first').before(container.find(elm + ':last'));
    resetSlides();


    //if user clicked on prev button

    $('#buttonsabc a').click(function(e) {
      //slide the item

      if (container.is(':animated')) {
        return false;
      }
      if (e.target.id == previous) {
        container.stop().animate({
          'top': 0
        }, 1500, function() {
          container.find(elm + ':first').before(container.find(elm + ':last'));
          resetSlides();
        });
      }

      if (e.target.id == next) {
        container.stop().animate({
          'top': item_height * -2
        }, 1500, function() {
          container.find(elm + ':last').after(container.find(elm + ':first'));
          resetSlides();
        });
      }
      //cancel the link behavior            
      return false;

    });

    //if mouse hover, pause the auto rotation, otherwise rotate it    
    container.parent().mouseenter(function() {
      clearInterval(run);
    }).mouseleave(function() {
      run = setInterval(rotate, speed);
    });


    function resetSlides() {
      //and adjust the container so current is in the frame
      container.css({
        'top': -1 * item_height
      });
    }

  });
});
//a simple function to click next link
//a timer will call this function, and the rotation will begin

function rotate() {
  jQuery('#nextabc').click();
}

Why dont you use the callback of load() function?

$("#jobshome").load("jobs/newest-jobs .js-toprow", () => {
   //do stuff after loading the html
}); 

when doesn't work because it expects a Promise or Deferred object and if its neither it treats the value passed as a resolved Deferred (which basically means it doesn't wait, but executes then/done right away).
