Generally, it is reasonable to go back 10 â 15 years in your work history. If you have a longer work history than that, you can divide your work history into two sections, recent and relevant, or include a separate paragraph that summarizes all relevant prior experience.
It is important to remember the main differences between the parliamentary and the presidential system of government: the main is the election of the executive powers, the debate styles and the position of the president on two posts at once: the head of the state and the chief executive.
In presidential systems, the powers of the two houses are often similar or equal, while in federations, the upper house typically represents the federation's component states. This is a case with the supranational legislature of the European Union.
