Former Amazon principal engineer, Steve Huynh, emphasized the importance of Amazon's 'reading culture' which involved daily reading of six-page memos for 1-4 hours.
Huynh mentioned that Amazon's culture of writing and reading was considered the company's 'secret sauce' and other companies should strive to replicate it.
Amazon's memo-writing culture was instilled by Jeff Bezos, where employees would share dense, direct six-page memos rather than using PowerPoint for presentations.
Andy Jassy, Bezos' successor and Amazon's current CEO, has continued the culture of memo-writing, emphasizing the effectiveness of concise six-page memos for communication.
