An essay is a free-form essay that expresses and argues the author's position on an issue. Although essays are mostly associated with literature classes at school or do my math homework at university, some people also write them when applying for a job. For an employer, an essay is an additional way to evaluate a potential employee. All because of the highly competitive job market: when there are a lot of great candidates around, you need to bring out the best of the best. With the help of the essay the employer also evaluates the communication skills of the candidate: the ability to write a competent business letter, the ability to clearly state and argue his thoughts.
