no need to extend any objects just return an object from the service like so:

```javascript

  .factory('interviewQuestion', function ($http) {
    // Build an interview questions class
    var endpoint = 'http://127.0.0.1:3000/v1/interview/questions';
    return {
       get: function()...,
       getAll: function()...,
       create: function()...,
       delete: function()...,
    }
);
```

makes it more simple
