What kind of job is it for?
if it's an ICT technician job you don't want to say technology.
if it's an accountancy job, you don't want to say statistics.
if it's a vetinary job, then you don't want to say, a fear of animals.
if it's in a shop/restaurant, you don't want to say that you hate people.
it needs to be vaguely relevant to the job, but not so relevant/ major that you couldn't do your job properly.
