Trending @Cognizant; Does Cognizant have a policy for sabbatical or long unpaid leave for exam preparation?

"Hi everyone, I am planning to take a break of 3–4 months to prepare for an important competitive exam. I wanted to check — does Cognizant have any policy regarding sabbatical leave or long unpaid leave for exam preparation? If yes, what is the process to apply and get it approved? Any inputs or guidance would be really helpful. Thank you!"
