What is one common mistake made in résumés?

Writing in an unprofessional format is indeed a common mistake made in résumés. A résumé serves as a first impression to potential employers, and its presentation is crucial. An unprofessional format can include inconsistent font styles, inappropriate use of color or graphics, awkward layouts, or excessive text without clear organization. Such formatting issues can distract from the content and make it harder for hiring managers to quickly identify a candidate's qualifications. A well-structured, clean, and professional résumé not only showcases the candidate's qualifications effectively but also reflects their attention to detail and professionalism, which are highly valued in the job market.

In contrast, including too many skills can sometimes dilute the focus on the most pertinent qualifications; completing it on time, while important, is not a common mistake; and having no references listed may depend on the expectations of the industry or specific job application, but it is not typically categorized as a formatting issue.
