Hello,

Nobody can recommend you the "best" specialization for M. Tech.

Basically, a specialization after your graduation depends completely on your passion, interest and the industrial requirement. If you are not particular about any field, better assess yourself and take up one specialization that will have demand for at least next 5 to 6 years.

If you are looking for a job in teaching, better go for M.Tech CSE. The reason is most of the colleges have a feeling that if you are specialized in any area, the basics of CSE may be missing in you.

Currently, the most booming market for Computer Engineers is in these two fields: A.I and Machine learning.

I'd definitely recommend you to get a master's degree in any of them.

And please always remember "nothing good comes easy". So, the words 'best' and 'easy' just don't go together.
