Before and after.

Photographs comparing before and after home remodeling projects or scenes of beautiful landscapes and communities destroyed by flood or fire and how they are reclaimed and rebuilt, create startling, striking images.  They are memorable.

The use of before and after performance comparisons on your resume and in job interviews also provide powerful examples for  your narrative.  In telling your story, the successful contrasting of the before and after impact of your efforts can leave a vivd impression in the mind of the decision-maker. 

That is exactly what you want to do.  Be memorable.
