When the Instagram Stories project was churning, leadership made a counterintuitive move: they significantly cut the team size. This resulted in clearer ownership, less communication overhead, and faster decision-making, allowing a tiny core team to build and ship the massive feature in just a few months.
The launch of Instagram's now-iconic gradient logo was met with widespread public ridicule on Twitter. However, internal data revealed the opposite: the more vibrant icon was more visible on users' home screens, materially increasing how many people opened the app each day.
Ryan Peterman, who became a top engineer at Instagram, initially failed his Facebook interview. The interviewer ended it early, stating he wasn't good enough. This demonstrates that a single, high-stakes interview performance is a poor predictor of long-term career success and resilience.
Ryan Peterman's internship at Flipboard included future founders of Figma (Dylan Field) and OpenSea (Devin Finzer). This highlights that early-career roles at startups with high talent density can offer superior networking and learning opportunities compared to more structured programs at larger tech companies.
For Instagram's "Whiteout" redesign, co-founder and CTO Mike Krieger's initial directive was to "build and ship it" without A/B testing. This reflects a philosophy that for major, vision-driven product changes, data-driven incrementalism can be a trap, preventing the big leaps necessary for innovation.
To combat severe physical anxiety that caused him to fail his first Facebook interview, Ryan Peterman got a prescription for beta blockers. These drugs block adrenaline's physical effects, like a pounding heart or shaking hands, allowing him to stay calm and pass his full-time interview loop.
Inside Instagram, engineers frequently discussed a thought experiment: if half the company vanished, would things improve? They often concluded "yeah, maybe." This reveals a deep-seated belief among product builders that organizational bloat, communication overhead, and excessive code were creating more problems than the extra headcount was solving.
For engineers working on user-facing features, the highest-leverage partnership isn't with a senior technical architect, but with a top-tier designer. Ryan Peterman's strategy was to become the go-to engineer for the best designers, allowing their exceptional product sense and vision to flow through his work, multiplying his own impact.
Despite building "Flex," a popular open-source iOS debugging tool later used internally at Facebook, Ryan Peterman's interviewers at Instagram showed no interest in it. They focused solely on algorithm questions, highlighting a disconnect between real-world impact and standardized hiring processes at large companies.
Convinced he was underleveled as an IC4, Ryan Peterman explicitly asked his director to be promoted two levels to IC6 in one cycle. While HR policy prevented the double jump, the bold request successfully anchored his manager's perception of his performance at a higher level, leading to two consecutive promotions.
Ryan Peterman joined Instagram's iOS team after two warring factions had "destroyed each other" and left. This "post-war" environment was full of low-hanging fruit, enabling him to make immediate, massive impacts like cutting the crash rate by 80% with a one-line change, accelerating his career.
Near the launch of Instagram Stories, the team was in a bind after losing their drawing tools engineer. Co-founder and CTO Mike Krieger exemplified a "lead from the front" mentality by personally jumping in to code the remaining features, like the neon brush, and review diffs at 2 AM. This hands-on leadership from the top inspired the team.
The now-ubiquitous "hold to pause" feature in Stories was created because engineer Ryan Peterman felt it should exist while dogfooding the product. He instinctively tried to pause a video with his thumb, and when it didn't work, he simply built it. This shows how engineers can drive product innovation by implementing their own user instincts.
