Job titles in most countries are usually determined by the person’s position in the hierarchy, their payment and whether they are legally allowed to represent their company and sign contracts, for example. This is not always the case in the U.S and U.K and other English - Speaking countries. The job titles often give you no indication of the person’s responsibilities because each company has a different structure and operates under different rules. Thus A vice president in one org may have a very different job description from a vp in another company.
