Every essay should begin with an introduction, then move into the body of the essay, and finally end with a conclusion. The introduction and conclusion should each be no more than a paragraph or two in length. The main body of your essay contains the points you make regarding the essay topic. The length of this portion will depend on the requirements given by your potential employer and the complexity of the topic. If the application essay asks for two examples, make sure you follow these specific directions -- this helps an employer identify you as a job candidate who can follow directions.
