In my current employer recruitment looks like this: team members go to interview with candidate. Later team talks about who that was (name), where it works now, who maybe worked there previously, how the interview went or even get a copy of CV. It's totaly not OK for the candidate and it violates law (especially GDPR things, I'm in Europe).
Now I'm on the other side of the table and I'm looking for the job. I supose that other companies handle things the same way - as soon as my proposal lands there, everybody knows that.
What's wrong with it? I don't want my current employer to know that I'm looking for new job. And people from my possible new company may tell people from my current company that I was there on an interview and I become "uncertain", "searching" etc.
This is obviously disclosure of my personal data. Should I inform the first line recruiter (that is when sending my offer email, or the first HR telephone call human) explicitly that "I really care about privacy of my proposal and disclosure is not welcome"? This is kind of obvious, but once it happens, even if they will admit to be sorry - the milk has spilled.
EDIT about passing candidate data around: It's OK to pass CV around for people intended to be in interview process. It's NOK to pass it to people not involved in it - especially it's NOK to spread word outside of company, e.g. during private / business talks with other people - this violates GDPR and is simply put not fair. So for example you can pass CV to other team member to evaluate it; but you can't pass it to colleague from other department with note "hey I think you know this candidate wife"; and can't read somebody's CV aloud in 100 people open space and laugh at it (I've seen this happening, it was before GDPR was intrduced but this is true).
