Don’t use out-dated or unprofessional contact details. Always use the most recent, most relevant, and the most professional
Don’t simply copy or rewrite your resume
Don’t include irrelevant information. Consider the role, the specific needs of the employer and the company more broadly, and what they want most from candidates. Focus on these areas in your cover letter
Don’t use buzzwords. When overused they tend to lose meaning and impact
Don’t use company-specific language or terminology. Stick to what is known and understood at an industry level
