Hi there.

Let's say your official job title at your company is 'Sales Executive', but the work that you do is better known as 'Business Development Executive'.

NOTE: I'm not talking about amending hierarchy but rather functional title (e.g. Executive --> Executive; NOT Executive --> Snr. Manager).

Is it unethical/deceptive/illegal to amend job title on resume to better reflect the type of work you actually do (so that it paints a better picture and hence more relevant experience/keyword for the HR in your job hunt)? Would it negatively affect employment background check?

Would appreciate experienced HR thoughts on this. Thanks!
