Nothing, not at all one thing scammers all the way
Svantaggi
The HR is a entitled guy in the hands of management, just see his reply above to a text, been here for 6 months, never have been more abused in money, they don't pay above 2.5lpa to devs, will hire you as interns and make you do projects in 20k with immense work pressure over all exploiting your skills !
