Communicating quickly and effectively is the cornerstone of any profession. No matter how unrelated writing may seem to a particular field, it's important to regard your writing as an essential component of your skillset.
The importance of good writing skills begins at the hiring level. Cover letters are an integral part of many hiring processes, and candidates who display excellent writing skills often stand out in the application pool. The importance of showcasing good writing during the hiring stage extends to email conversations with prospective employers as well as effective resume writing.
Although many modern workplaces have become more casual regarding communication, maintaining professionalism across email correspondences or other written exchanges remains important. Responses riddled with typos or confusing and improper grammar may cause co-workers or superiors to question your professionalism or attention to detail.
