there are indeed such cases. it's either it hasn't been updated internally after a requirement review or in most cases, the third-party job portal system auto update by generating the old template. it can happen if the requirements are just changed recently. certain roles will be reviewed if there's a misjudgement of initial requirements (eg. few batches of fresh grads can't perform, 2 years experience insufficient for required jobscope etc) or when new responsibilities are added in. remunerations will often be adjusted during a review.
