MBA sponsorship is usually not automatic. Eligibility often depends on tenure, performance, office policy, and whether you are in good standing when you apply.
The exact rules differ by firm and office, so use the consulting-firm MBA sponsorship guide as a starting point and then confirm the current policy internally.
Treat sponsorship as something you qualify for through your employment record rather than a guaranteed employee benefit. If an MBA is part of your plan, ask early enough to understand timing, approved schools, and return obligations.
