Hi Rinku!
Yes, IIT Varanasi (BHU) offers good placement opportunities especially to student of CS in the companies such as  HP, Paytm, Goldman Sachs, Amazon, Google, Microsoft , Facebook and many others with highest salary package 2 crores per annum till now and lowest salary package of 5 LPA. But students of MSc (CS) are least preferred by the recruiting companies as first preference is given to the students of B.Tech CSE.

So, yes placements are there for MSc students but less than compared to BTech students.

Hope I answered your query, thankyou!
