If you want to show social icons for each candidate, you can have nested ng-repeat as shown something like below:

<div ng-repeat="candidate in candidates">
    <div ng-repeat="socialLink in candidate.socialmedia">
       <a href="{{socialLink.url}}"><div class="{{socialLink.network}}></a>
    </div>
</div>

You can define some css classes based on the socialmedia networks and use those class names in your html to display the images (check the below css for your reference. This is just an example for your understanding and not the exact css definitions you will use)

.facebook {
  display: inline-block;
  background-image: url("facebook-icon.png");
}
.linkedin {
  display: inline-block;
  background-image: url("linkedin-icon.png");
}
.another-network {
  display: inline-block;
  background-image: url("another-network-icon.png");
}

Try like this :

    var test={
"candidates": [
    {
        "id": "0",
        "socialmedia": [
            {
                "network": "facebook",
                "url": "https://www.facebook.com"
            },{
                "network": "linkend",
                "url": "https://www.linkend.com"
            },{
                "network": "skype",
                "url": "https://www.skype.com"
            },{
                "network": "google",
                "url": "https://www.google.com"
            },{
                "network": "yahoo",
                "url": "https://www.google.com"
            }
        ]
    }
]
}; 
var socialmedia=test.candidates[0].socialmedia;
for(var i in socialmedia){
alert(socialmedia[i].url);
}

You Have to store the response in $scope variable like this

$scope.socialmedia=response.candidates[0].socialmedia;

In Your View

 <div ng-repeat="img in socialmedia">
    <img ng-src="img/{{img.network}}.jpeg" >
    </div>

Note the images should be stored in your www folder, based on the name it will display or else you can directly call it from server
