I have applied to a company in the EU. The person handling this process is in touch with someone (say, a campus ambassador) in my university (to advertise this opportunity in our university; there are no personal links between them). For various reasons, I don't them to know that I've applied to this company. I want to know if this company will disclose (for example, if say, this campus ambassador asks them how many people have applied to them from our campus and their names).
Does any EU law prevent them from sharing this information? Logically, there's no reason to share. But could someone just casually share that I've applied in response to a query?
