What is the difference between deloitte india and deloitte usi work culture wise

Can somebody help clear this up ?

Which one would you choose and why?

Hi Everyone.. I wanted to know what is the difference between Deloitte USI and Deloitte India? which one should apply for??? Are there any perk differences???

I heard that the work culture at Deloitte is bad that people work for 15 hours a day? What's happening at Deloitte?
