Bob is the HR manager of a

very large liquor store. He dismissed Mr Kirsten who was appointed as the

accountant. Mr Kirsten recorded transactions incorrectly to cover up acts of

dishonesty. Bob urgently needs to appoint another accountant and asks his

friend, Mr Moloto, who is also a manager of a liquor store, to recommend a

competent and honest accountant. What is the method of recruitment used in this

scenario?
