Biotechnology

It depends on your interests and career plan. The options after B.Sc in Biotech would be to do your Master's degree 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 organizations such as Biocon, You should be really good with your basics on concepts such as Fermentation technology, Bio-remediation etc. However, its worthwhile doing your Masters and your doctoral studies Ph.D. 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.

B.Sc is the best path if your aim is to make your career in the research or academic field because the course is more focused on pure Biology plus (B.Sc+M.Sc takes 5 years) so in the 6th year, you can join Ph.D. B.Tech is best option if your aim is to get an industrial job because when you go to aqn engineering college most probably the only department with biology involved will be biotech in the entire college and engineering is a mix of different courses, the initial year you will learn (Mech - ECE -Civil, etc.). But later it will be more of equipping your industrial knowledge in the last semesters it will be a mix of Biotech and Chemistry plus (B.Tech+ M.Tech takes 6 years) so only in the 7th year, you can join Ph.D in Biotechnology with initial Bachelor's degree just being a basic knowledge so it is must do a Master's degree. If you want to continue in the same field irrespective of B.Sc or B.Tech.

Scope can be categorised in several ways. So, I am writing in two major sections so that one can use it as per the broad interest.
Employability:
Pharmacy gives better employability as compared to biotech, biochem or microbio. The reason is the huge pharma industry. B.Pharma. Itself give you an okay job while M.Pharma. May give you a reasonably decent job. Pharma sector includes several fields of work from research, development and manufacturing to sales and distribution. All these fields require huge number of manpower. So pharma sector wins this employability criteria. Although most of the jobs are in private sector but quantum is huge too. Other three fields also give private sector jobs but in India such field for life sciences is still growing. Masters in life sciences rarely brings a good job opportunity. Research/Academia
Pharma research is not well developed in India as compared to life sciences. Research requires post M.Sc. Work and biotech, biochem and microbio are similar in this aspect. The reason is that most of the research institutions in our country give equal preference for M.Sc. Biotech, biochem, and microbio or other life sciences students while selecting them for Ph.D. or a project work. So if one wants to do research, he/she should opt for either of these three fields in Masters. Academics require publication. All these fields are publication friendly. All these fields can be a good platform for becoming an academician. Though lack of research and more opportunity in private sector in pharma, makes pharma more job oriented and less academia-oriented field here. While other three are more academia oriented because of well-developed research infrastructure and low private sector opportunity. *Finally, choose whatever you like. Recognise your passion. You cannot spend your life doing the work you don't like. Some people want money first so may opt for pharma, some people want to do research so may opt for other three fields. Ultimately, it's your choice what you want to see yourself in the future.

M.Sc is a science programme and M.Tech, the technology programme. It is crucial to understand the basic difference between Science and Technology. In India, the case of having Master's degree in science is a bit convenient as it necessitates three years Bachelor's degree, nevertheless, Master's degree programme in technology requires four years Bachelor's degree or two years Master's degree in science. Also, there is a major difference that technology courses are usually expensive as it has commercial value, for which the courses are taught accordingly. Science is not time-bound, whereas, technology keeps on changing with time. Job post M.Sc and M.Tech-industries prefer M.Tech people more as they are coming from the engineering background. M.Tech graduates are paid more in industrial sectors compared to M.Sc to some extent, M.Tech graduates have an upper hand over M.Sc professionals.
