If you do not have the time to review and correct your resume, then that is what the potential employer will think of you as being the quality of work as well as lack of attention to detail that you will bring to their organization. Remember that accuracy is very important. The Hospitality Industry is very small community. Do not assume the reader of your resume is uninformed. Do not brag about accomplishments you had no control over.
Most candidates do their own resumes.
This is fine if you spend some time with it and pay attention to the points mentioned here. Otherwise, consider a resume service that specializes in resume writing and production. You are ultimately responsible for the content. A resume service will generally not be aware of our industry jargon. Furthermore, before you select a service, ask to see some samples of their work.
