This query is identical to the GET query above except that the geoids are
to be POSTed in a json array rather than appending them to the querystring.
This should be used if you have too many areas to fit into a query string.
Returns a list of all careers with data corresponding to the geographical area(s) specified.
There are four query keys that you can pass: category, pathway, fields, nocs.
The fields key is always required as there is no default return object.
