Palpable Score

79
/ 100
Mastercard is a strong early-career option because Mastercard runs paid internships with a stated path into the Launch graduate program, and Mastercard also backs recent grads with an 18-month structured development journey. The main limits are predictability and consistency across teams: candidates report a wide range of interview styles depending on role, and the company’s pay transparency is strong in some markets but not universal.
