Hello aspirant,

Current status of M tech in Environmental engineering  is

1. Most of Post gradution as of M tech , institutes are not well adquate about teaching and providing thorugh knowledege about branch.
2. This branch awareness has grown but Institutes only suck money but never give you exposure of industry and placements.
3. Suppose you complete mtech but getting jobs is highly difficult because of no field knowledge and for design you don't have experience .
4. Anyhow if you get jobs what shall be salary ..it's less than b tech fresher gets  ..around 10k-15k .
5. I prefer you do Post graduation in Environmental engineering either from IIT or Abroad (M S)
6. Only advantage of doing M tech is you can go for teaching line and pursue PhD  and PhD will depend upon guide selection and research arena .
7. These all above are facts and if you want know exactly .. Visit all aluminis and ask their opinion .
