Cashfree paymemts offer

I am graduating this year. I have an SDE-1 offer from cash-free payments. CTC:39 -> 25.5 LPA(including esops) I didn't find much info about the company. So I want to know about the kind of work I can expect and the work culture at the company and also any information that helps me as a newbie in the industry.

Thanks in advance.
