Hello,
I recently started receiving emails from recruiters claiming to be from competitors (Citadel/MLP). The messages are very obviously generated from my LinkedIn profile, and the sender addresses look like firstname.lastname.career.citadel@gmail.com, which seems suspicious. I would expect legitimate recruiter emails to come from an @citadel.com (or company) domain.
Has anyone else received similar emails? What do you think the goal is? Could these be independent headhunters using Gmail accounts in the hope of getting a higher response rate, or is there something else going on?
