One of my friends studied at NIT Goa. According to him, In the recent placement drive of 2021, the students of NIT Goa were offered the highest packages compared to the placement drives of the previous years. 

• One of the students who completed the M.Tech course got a package that offered INR 14.3 LPA. 
• The companies that have made offers to the students this year are Siemens, Goldman Sachs, TCS, Samsung, Mphasis, Samsung, etc.
• In the department of CSE, out of the 27 eligible students, all 27 of them got placed, making their placement program a complete success. 
• Over 45 companies have visited NIT Goa in 2021 so far; surpassing the tally of the previous three years.
• If we talk about facilities, the labs have computers that are high end and run on Linux and Windows operating systems. 
• The internet connection provided, leaves no room for complaints.
• The campus is wifi enabled too.
• The faculty is helpful and cooperative.

So it is suggested that if you want to opt for M.Tech in CSE from NIT Goa, you may go for it. As not only placements, but they also offer research facilities too. You will be able to publish research papers and work on your thesis and dissertation.
