Booh and hiss. The latest job scam is in. I've received two such scams that seem like a genuine reply to an application, but they have one "tiny" request: Just click on "this link here" and get a "free" credit report, and then we'll set you up for an interview. Hmmm...I know better than to click on such links, and, likely this link will lead to a scam or phish site, or perhaps prompt the user to fund a subscription of some sort. Really, the amount of time that people spend on crafting these scams is obscene.
Your best defense: think about all replies logically. If a company asks you to perform some task beyond a standard questionnaire before coming in for an interview, ask questions about WHY you are being asked to do so. The first time I received a request for my credit report, I emailed back asking why this step was neccessary, and whether I could complete this step AFTER the interview instead of beforehand. Guess what! Crickets. No reply, whatsoever. No harm in questioning the motive. Very few employers request credit reports, and, if they do, it's once you've hit the final round of employment.
