I've had Infosys and TCS reach out to me, and when pressed for salary figures said the upper end was a half of my current salary, and this is in Australia. I'm not even on a particularly high salary, could have gotten a ~30% pay rise had I joined an industry I wasn't keen on... Not convinced it isn't some sort of legal obligation thing to bring in cheap labour, or just preying on people who need a quick job to maintain their visa obligations. Offering {minimum_wage + 30%} for a software engineer with a few years of experience seems like an exercise in futility otherwise.
