Highlights:
Companies I like:
Ziff Media Inc.(Electronic Gaming Monthly), Microsoft Game Studios, Nintendo, Capcom, Konami, Game Arts (they still around even?), SNK/Playmore, Namco (only the japanese division, though. The american branch of the business hasn't made a good game since....ever), Square Enix, Working Designs, Blizzard.
Are you really being serious? How many people do you have applying for this position that have made a "significant impact" on their prior organizations/places of employment? Seriously, if anyone had ever made any significant leaps and bounds in their particular fields of expertise, they wouldn't be writing this up.
As for responsibilities that I believe would prove my worth as a valuable employee to you (NONE i would ever categorize as SIGNIFICANT, mind you)?
I have worked at various video rental stores where i was in full control of all of the companies money and premises (I closed regularly). I have also done customer service for Verizon Wireless, by far the most patience-taxing job I have ever had thus far in my life. People concerned with their phone bills are rarely ever pleasant.
