I admit I would try to answer in the "right" way, or the answers that I suspect they want for the job, but without outright lying (if that makes sense). I go in with the assumption that my natural personality would have major bias against it (even though at every job I've had, the employers grew quite attached to me & were sad when I left; even at the job I "lost", I was the last one getting paid before they went under). I don't think this assumption is wrong, given how people react to INFP profiles.
When I was desperate for work, I was applying to minimum wage jobs, which all make you apply online now & many use a personality test of sorts (nothing like MBTI). I answered in the way I thought was right, but later discovered it was not, as the connotations of many questions were interpreted VERY differently by me (ie. "Are you a risk taker?" - I interpret that as someone who goes sky-diving sans a parachute or eats exotic foods that could kill you or maybe embezzles from their employer....but nope, they just mean someone who goes out of their comfort zone & above their job description at times. Needless to say, I answered no when the answer was supposed to be yes). They also had "degrees" you could answer in, and apparently, only no or yes were ever right, not anything inbetween, which they took to mean you are not decisive or something silly like that (but with 100 different perspectives & possibilities, how could I definitely answer yes/no without more specifics?!!!). The right answers sounded like ESxx types, yes. I also found out they did not want people TOO smart or educated... for turnover reasons (likely to leave for something better and/or go after a management job).
Anyhow, they never really asked questions which got at my strengths, but perhaps that's because they are not in retail. That said, in college I did fine in my part-time, retail jobs. Those managers were sad to see me go too. They have high turnover & I stuck around longer than most (as many in those jobs just don't show up to work one day; was surprised at how flaky retail people are), was the type to kindly fill in for a co-worker if they wanted a day off, and was quite pleasant to customers (albeit no aggressive sales). But you know, I don't use alligators for water-skiing in the amazon, so I'm not a risk-taker & not well-suited to ringing up cheap clothing for teenage girls.
