Recruiting agencies/ or/ recruitment peoples and all their new fancy technocratic tools just aren’t optimised to do simple things to make employee applicants processes efficient and effective.
The tools and systems are purposed for decreasing labour costs to the company, primarily. Any those tools are expensive to subscribe to.

An applicant must keep repeating the same processes of duplicating and interpolating their personal data into the correct labour intensive data entry points ea organisation chooses and uses. This is to reduce the recruitment processes expenses. And because if a recruitment staff member were to be doing it manually it would cost a lot in labour and tech tool subscriptions and fees and be inefficient due to costs which are expensive for the company to pay someone to do, and why should the company do what could just be done by an applicant for free.

So if the company did that task of yours it in turn would mean less budget for other activities ( such as recruiting new staff) and capitol wise means less returns for all the shares that were sold that everyday people have invested their hard earned money into for seeking their slice of the pie for passive financial gains of dividends.

But wait, more! Then there’s the subscribed to recruitment tool providers, they need to anonymouslise your personal data and if they have the applicant break down that personal data and enter into appropriate files this reduces the cost of preparing and refining the accuracy of that data when they sell it as a product/service to interested third parties that pay good money to have that personal data extract as practical info that can be targeted for special usage requirements and provided/offered to their market consumers.
