I would bet that most companies vastly overestimate their initial engineering requirements and thus their talent requirements. A past job had a strong interest in scalability when the software serviced maybe a 20-30 (admittedly high value) people an hour. Even their loftiest ambitions maybe put use into the hundreds or low 1000 an hour.

Yet most engineers were hired with the goal of making it "scalable" when most of the work was frontend anyway.
