Good question!

We generally differentiate between Full time, Part time, Temporary and Free lance jobs. We then have a category called Sectors, so which field your job belongs in. We then have Industry and Career Level, which are fields that are used when a job is posted. We also have a category called Internal, which we use for jobs internally at our company. Other jobs are external, which means they go to an external website, usually the job portal of the company you are applying for.
