Generally, there are no guidelines on how much dataof a candidate should be
saved in a company. However, it should be "as much data as necessary and as
little as possible". When Applications are done by mail, the data are also
limited by the scope of the application documents. On the other hand, online
applications can be made in a contact form that is created by the company and
posted on the company's own homepage. When preparing such a form, the
company would make sure that only relevant data are requested from the
applicant.
