While the idea that "bullshit jobs" are common may itself be bullshit [1], one can imagine that at companies like Google whose major task is preserving their current market position rather than innovating to enter new markets, and who allegedly employ smart engineers simply to prevent their competitors from employing smart engineers, there is a higher than usual level of bullshitness.
[1] From Wikipedia: Using data from the EU-conducted European Working Conditions Survey, the study found that a low and declining proportion of employees considered their jobs to be "rarely" or "never" useful."[14] The study also found that while there was some correlation between occupation and feelings of uselessness, they did not correspond neatly with Graeber's analysis; bullshit "taskmasters" and "goons" such as hedge-fund managers or lobbyists were vastly satisfied with their work, while essential workers like refuse collectors and cleaners often felt their jobs were useless.
