Just to clarify, salaries in India differ VASTLY across companies, FAANG or otherwise, depending on whether the org looks at the India center as a cost-saving measure, or as a secondary RnD center. And also, if the org is more services based (the notorious Infy/Wipro/Accenture types) or actually building products. The latter almost always pays more.

I'm a non-IIT Masters graduate with 3.5 years of experience and I work at the India center of a non-FAANG US-based company, and I make more than @sures made with 10 YoE (leaving aside stock options as well).

Salaries are higher in cities like Bangalore and Pune, but even there the salary ranges are very varied, so it's difficult to get a representative sample. Funnily, if you check on Glassdoor (for what it's worth), you'll find companies (both Indian and US/UK-based) where Director of Engineering in India as much as I make with <4 years of experience.

Also, Indian companies are notorious for asking previous salary details/payslips etc before making offers. As such, if you start off at the lower end of the spectrum, you spend a lifetime playing catch up. Usual hikes between job switches is about 1.4-1.6x, so the 2x jump @sures got in 2015 is also not that common (Well negotiated @sures!) :)
