Good company to work with strict HR policies. Employees rights are taken care properly.
Documentation: The document validation is done by third party. Beware invalid documents because you won't be able to sustain long in the company max 3 month till the time documentation is done.
This is time consuming process and very irritating even if you have to submit the document they may ask you submit the such copies again and again until they are satisfied with the validation part.
Opportunities to grow : you will have ample of opportunities flowing your ways with ease only thing you will have perform which is obvious.
Salary : I think it would depend on your current salary. If you are a fresher would be the right choice to go ahead in your career. 15k and above for fresher's as per their interview.
