Hello Ashok,
The admission into B.Tech biotechnology at VIT Vellore is based on the ranks that you get in VITEEE. You need to opt for PCBE and not PCME.
For more information you may refer: www.vit.ac.in.

Hello Shivi,
There are no separate seats for NRIs. You need to apply for the same procedure as the resident Indian nationals. Only foreign nationals have a separate procedure.
The admission is based on an entrance test called VITEEE.
For more information you may refer:

It is considered so because of nearly no placements and poor quality of teaching.

Sorry in Annamalai University, they will not grant you admission if you have not completed 10+2.
As per NCTE norms, regular teachers working in primary, middle, secondary or higher secondary schools in Tamilnadu, recognized by State / Central government, with a minimum of two years teaching experience are only eligible for admission into Annamalai University Distance Education B.Ed course.

Coimbatore colleges are better when compare to chennai!
