It's critically important to consider your audience when writing your resume. Here are 3 things to think about:
1. You'll waste their time if you tell them what they already know.
For example, if you're a district manager and you tell them that you conduct store visits, identify opportunities for improvement, and create action plans, you've wasted their time - retail recruiters already know what district managers do. After all, they come from the retail industry and they recruit people like you for a living. They're also smart people (most of them).
2. You'll confuse them if you assume too much.
Yes, I know I just said retail recruiters are smart people, but that doesn't mean they know EVERYTHING. In all likelihood, they've worked in retail before but that doesn't mean they worked for the same companies you did. So avoid the use of company-specific jargon, acronyms, or anything else that the reader may not know. (Hint: They probably know that P&L means profit & loss, but they may not know ADS is average dollars-per-sale because their past companies may have used something like DPT - dollars-per-transaction.)
3. You'll frustrate them if you're vague instead of specific.
Avoid words like many, several, extensive, numerous, etc. - they mean something different to everyone, and they provide the reader with very little value. (I've read so many times that someone promoted "countless" managers. What is that exactly? 10? 100? Who knows?) Be specific. "Promoted countless managers internally" tells the reader very little; "promoted more than 50 managers internally" tells them something of value.
Hope this is helpful. Best of luck on your job search!
