Leveling up in the same org is all about the company's cost. Some companies(especially bigger ones with names that attract new grads) will deny you a promotion if they believe you are cheap to replace(denying a promotion often leads to employee unsatisfaction which causes them to leave). Most companies, especially if they are having problems finding new engineers, will just give you a promotion to keep you happy and because they can't afford the time and costs of losing and employee, find and train the next one. However, I think the article is more about personal improvement than proper leveling up within an organization, in which case it's not about being noticed.
