Most resume formats, require you to mention the details of positions held.
This normally includes, designation, dates, company name, location and??

That's right, AND??

This is where you sell yourself.

Remember, the recruiter doesn't know you, let alone your achievements.

So here are some guidelines:

> List only 3 accomplishments per job position listed- anymore and you risk sounding pompous!

>List only facts - no feelings.
Facts can be verified. Feelings are subjective. 

Revenue, Sales, Costs, training hours/man day, launch of new products/services

Good examples|

• increased revenues for 08-09 by 45%, reduced attrition by 30% on a YoY basis

avoidable |

• staff was happiest under me, customers kept asking for me by name

>List only those that demonstrate the skills that the job you applying for requires.

>List only those that are used to measure success for the designation you were in when you accomplished them.
