SVNIT witnesses decent M.Tech placements. But for someone who wishes to work as a teacher, there are good options. This is because a large number of colleges and coaching institutes visit the campus for recruitment. The companies look for a certain specialization, in accordance with the job requirements.
Intel and Marvell Semiconductor visit the campus seeking VLSI, Communication systems and Computer Science students. They do not make direct recruitments. Instead, they hire students as interns and then later offer them PPOs.
Bombardier, Qualcomm and General Electric hire from M.Tech Electrical. L & T hires Civil and Mechanical students, and WSP hires Civil students. Akash institute, Base and WiFi visit for teaching recruitments.
M.Tech placements are average at even the IITs. I would recommend you look for off-campus placements as well.
