Meta offers multiple credible early-career doors, including internships, “University Grad” roles, and rotational programs that are explicitly positioned as immersive learning experiences. Pay signals look competitive and often transparent via published ranges and widely reported intern and new-grad compensation, but early-career predictability is reduced by mixed candidate experiences and widely reported workforce churn in parts of the business.
