If you have heard on the grapevine that there is a position at a company, you may either work for the company already or you may have a friend who has informed you of a position and you would very much be interested.
An employer may want to know where you have heard about their future recruitment plans and this is where you need to be careful so that you do not get anyone into trouble. If it is a friend who has advised you to apply, would your friend consider approaching the manager and telling them that they have a friend interested in the role so that you can freely apply? If not then it may be a case of you applying on a speculative basis and maybe referring to your friend as someone who recommended the company to you. A lot of companies operate a recommend a friend system for vacancies so it will all depend on the company type.
