Hello,
Every year various companies visit IIT campuses across India to recruit engineering students in multi national companies. Software companies like google and microsoft recruit students of Computer Science background for various roles such as software developer and data scientist. The package i.e. payment per annum varies from person to person and depends upon role offered in the company.
However for domestic postings i.e. postings within India the package starts at around 15-20 lakh per annum and may go upto 30-40 lakhs per annum for top students.
You can visit official websites of respective IITs for accurate placement data of that college.
