<p>To be proficient in Excel takes more than trial and error which is different than “I can fumble through that pretty well.” Never learned Power Point–no need to. And I’m pretty good and sure I could come up to speed if required. There are 600 page manuals. The need for one depends on what you need to get out of the program–I created my own business program saving several thousand dollars for my employer. But maybe you wouldn’t hire me because I don’t do Power Point–now.</p>
