It is true that money matters a lot. In fact, if you worked honestly and with dedication; a good pay scale is your right. As far as my knowledge is concern about the pay scale of Mindtree, they can give Rs. 320000/-Per Year to an Engineer. It also depends upon their office location. The pay scale I am sharing here is for Bangalore location.
One more thing, this mentioned pay scale is for engineers only. For other vacancies it might be differ. The pay scale depends upon your experience and skills. If you are sharp and have good enough experience than there is no boundary for the salary.
