B.Sc

Hello Nilesh,
As there are many IT companies in India, there are many opportunities for computer science graduates. The salary for B.Sc computer science graduates may be a little low compared to M.Sc graduates. So, I advise you to do M.Sc computer science after 2-3 years of work experience. Following are some of the careers that I know in the field of Computer and IT:
1) Call Centers,
2) Computer-Aided Design
3) Computer Science Engineer
4) Hardware Engineer
5) Network Engineer
6) Software Engineer
7) Web Designer
8) Web Developer
