The M.Tech program of Environmental Geotechnology at NIT Calicut is an interdisciplinary branch.

In the first semester, you will be taught about Geotechnological Engineering and in the second semester, you will learn about subjects that are in Environmental Engineering such as Groundwater Hydrology.

All in all, this course is more towards the Geotechnical side than the Environmental side. You also have to undertake projects. Usually, most people opt for Geotechnical projects.

Talking about the prospects of the future, L&T has been the only recruiters for some years now they recruited very few students pursuing postgraduate. 

If you want to teach this course in the future, then pursuing it will be a good idea. It is definitely a good course but not the best. Join if you are interested in the course and not for the NIT tag.
