I just received an email regarding a job application, but I can't recall applying to this position since I've submitted hundreds of applications through Indeed. The email came from a Proton email address, which has raised my suspicions. Many commenters advised that the use of the word "kindly" is often a red flag for scams, and they suggested that this might be a ghost job posted by a recruiter. I’m feeling uncertain about whether I should respond or just ignore it altogether.
