Trending @Capgemini; Is there any benefit of taking interview in Capgemini?

Depends on your BU.. for each interview, you get 100-300 INR

I think he's asking for any monetary benefits.

Ofcourse it will help you boost your knowledge and refresh your skills. It builds confidence as well. Take it as a positive activity I would say while managing your day to day work

You can mention that in GetSuccess. Also it is expected from you(kind of) to do something for your BU apart from working in project.
