Entry-level management consulting is infamous for long hours and insane travel (pre-COVID, anyway). You're not going to have the time or energy for passion projects when you're spending every waking hour banging out PowerPoints and waiting for your connecting flight at O'Hare.
Three friends of mine are management consultant senior partners/associate partners at McKinsey. They echo the same - you're not going to be having the time or energy for passion projects or even family.
