Not just resumes either. I went through 2 interviews for a company, and then was suddenly ghosted after they'd collected the data they needed. They reached out to me, offering a position and when I told them how much I wanted for it (I didn't realize I'd told them less than they had it listed for, since I hadn't seen their job openings before being reached out to) they ghosted me and updated their job posting to match my desired pay
Similar thing happened to me. Got interviewed, told them my salary expectation, they turned me down and immediately published a new upper bound for the job's salary which just happened to be exactly 1000 € less per year than what I had asked for.
Lol restaurants don't have time for that shit. Who would buy that kind of data from a restaurant anyway? Even if you had more than 200 applicants a month that would probably net you less than $10.
doesn't need a chain. many companies save money offloading the application process to an external website, and that one manages it for a lot of different companies and then sells your data
