I'm not sure that's any less ethical than you "screwing over" the other blokes and blokesses who were interviewed along with you for your current job by using your superior skills, experience, etc.
Eh? Getting a job is the same as not finding your way to the bar? You need to recalibrate your ethics-detection instruments, mate.
Anyway. As a matter of fact I wasn't interviewed, I was hired directly by the CEO who I had worked for at another company.
