Hello,

If you want to get placed in TATA Steel, there is no direct recruitment as such. Firstly you should hope that TATA Steel or TISCO visits you campus and if they will offer campus placement then they will conduct an entrance exam followed by interview.
Of you want to do internship with them then you can apply through their official website.
Open their website and scroll to the end, you will see "Careers" option, click on that you will see option for internship. You can upload your resume and just hope for a response.
