Reapplication rules vary by firm, office, and where you exited the process. Do not assume that a new job posting automatically means your previous waiting period no longer applies.
The safest approach is to check the consulting reapplication guidance and confirm eligibility with recruiting if your prior communication gave you a specific timeline.
If you are allowed to reapply, make sure something meaningful has changed: stronger experience, clearer positioning, or better interview readiness. Submitting essentially the same application a few months later rarely adds much.
