So people should intentionally answer poorly on those questionnaires that companies give you when you are doing their online application process...the psych eval as I like to call it.
I would strongly recommend downplaying experience and careful but honest editing of resumés and applications. Custom tailor each resumé for each postion available. Unless it’s a position for which you’re actually a good fit and not overqualified, it’s really no time to toot your own horn. Play up what they’re interested in and give the rest short shrift.
There is no law that says you have to spell out everything you’ve ever done for your entire career, just be honest about what you do describe and don’t leave any gaps. Educational attainments and professional certifications can be omitted as well, depending upon the nature of the information that is asked of you. If it’s not asked, don’t volunteer, you’ll not make the impression you think you’re making.
Put yourself in their shoes, envision their ideal candidate and be it as much as possible given your unique circumstances.
