> Shortly after he turned 18, Google hired him as an L4 software engineer, a position typically offered to candidates with multiple years of professional experience as well as a college degree.
L4 is the entry level for Google's SWE position, and Google absolutely hires SWEs straight out of college (no professional experience). A Google SWE without a college degree is more rare but I know a few. I'd never heard of an 18-year-old landing a full-time Google SWE position, though. Congratulations to him!
edit: sorry, got mixed up, entry level is L3. Thanks for the correction.
