2. Not respecting the employer's time
The easier you make it for a hiring manager to read your resume, the more likely you'll get on their payroll. Resume reviews are as exciting to a decision maker as yesterday's stale coffee. Your resume should - in 20 seconds or less - show how you'll make or save money, generate new business, resurrect and retain existing clients or customers, expand and build relationships, and just make their world a safer and more pleasant place. Don't ever assume an employer knows what you're communicating.
