That's software in general. The core money-making algorithms don't take many human bodies to develop. At Google, 500-600 researchers and core algo developers likely do most of the heavy lifting. Otherwise, 90%+ of their developers are likely solving routine problems. Although, most of them likely convince themselves that only the "chosen ones" among mankind can do what they do. The reality is that most of software, even at the FAANGs, does not require the type of interview questions these teams enjoy asking.
