Hey Biswaprakash

Your question is not clear but I will try my best to help you out.

If you clear NET-LS, you can apply for teaching positions (assistant professor) in colleges and universities throughout the country with a minimum salary of 75,000 per month however qualifying NET does not guarantee that you will get the position of a lecturer, it is merely a criteria.

After getting your csir net certificate for lectureship, you  can apply for posts in various government universities and Private Universities too. You can also apply for Public Sector jobs in places like ISRO, IGCAR, TIFR,IISc,IVRI,IARI etc.
