This seems way off. The number of engineers working at FAANG is in the hundreds of thousands, an athlete that is 100000th best in the world is basically a hobbyist rando.
It's all relative. There are more professional software engineers than professional weight lifters. The top 1% work at FAANG, the top 1% go to the olympics.
The whole Olympic roster for the US is ~500 people. There's half a million people who are current NCAA athletes, that's an order of magnitude off right there, even after excluding football and before counting in the actual pros.
This example kind of falls apart with respect to the Olympics for an array of reasons. If you're looking at NCAA athletes, lots of those sports are not represented in the Olympics. Also, because spots in the Olympics are limited, the "best" person isn't always chosen to represent a given country for a given sport.
This thread is clearly about comparing the probabilities of getting into FAANG vs getting into the Olympics. The situation with varying relative competitiveness of the local "scene" in a particular country is the same in both cases, despite the fact that even the 1% figure for FAANG engineers would only work under the assumption of the global pool of candidates (~20 mil software engineers worldwide), all willing to relocate and prioritizing FAANG above all other employers (a lot of assumptions). Tldr: no, being kinda good at leetcode is not an Olympic-level feat, try the ICPC.
