Phishing for what? The amazon.jobs website only requires a login to... itself: amazon.jobs. So it is not phishing for your amazon.com login...

Many people reuse emails and passwords, so if such a victim sign up for scam.com, all of their other credentials were basically compromised too.

(Not saying that that's what's happening here. I initially suspected that amazon.jobs was a scam site; I think OP did too, hence the question.)
