IITs are synonymous for placements and opportunities. But if we have to pick one IIT among the rest, it will be IIT Kanpur. Their aerospace engineering department is almost 40 years old and they have one of the world's finest high-tech labs. You need to study atleast M.Tech to get a nice job in this field. To be honest, a Dual degree is of more value than that of B.Tech. Companies like ISRO, DRDO recruiting Candidates with M.Tech as an educational qualification makes this statement stronger even. IIT being an IIT draws a variety of recruiters like Siemens, Air Bus, Land Rover, PWC, JP Morgan Chase, etc. For complete information regarding their placements, please visit their official website at: http://spo.iitk.ac.in/assets/docs/2019-20/Brochure_AE.pdf
