It makes sense for Google and Big Tech since even in 2006, they were already profitable, and scaling quickly in usage and availability was always the priority. This was where the problems were unique to them at the time.
These startups today are trying to attract Googlers with the same interview process for no where near the salary or the equity and keep forgetting that they are not Google.
Every time you ask them why they need to ask for this specific algorithm and when was the last time they encountered it, their answer becomes close to lies and the truth is that they used a library or technologies created by Google.
