Biotechnology

Hello Monika,
An M.Sc Programme is a two-year course that introduces you to the subject in a detailed fashion. After completion of the course, you can normally go for research oriented job or technical job or opt for higher studies (PhD). M.Sc in specialized courses like Agriculture, Medical or Veterinary Biotechnology can be pursued only if you have obtained a specialized Bachelor's degree. Once you have obtained specialized degree, you may be absorbed in agriculture-based companies or R&D institutes involved in such activities.
Broadly categorizing jobs can be looked in both public and private sector.
Government sector offers jobs broadly under following categories. These are:
1. Administration & Policy Making
2. Research & Development
3. Technical Cadre
If you decide to join administrative line, after PhD you can join as a Scientist depending upon your experience. You can even reach up to the level of Secretary Head of the respective department.

It depends on your interests and career plan. The options after B.Sc in Biotech would be to do your Masters and then do your doctoral studies if you wish to be in the area of Research or a job in academia.
Some options are available for getting a job in the area of Production control or Quality Analyst in organisations such as Biocon, You should be really good with your basics on concepts such as Fermentation technology, Bio-remediation etc.
However, it's worthwhile doing your Masters and your doctoral studies (P.hd) and then trying for a job.
What really matters is your interest and the career plan that you have planned for yourself, whilst understanding your skills and what you are good at.
