Medicine & Health Sciences

Both the fields are good and have importance (as inter-related).
Considering job prospects I would say biotechnology comes first to bioinformatics:
Biotechnology is related to laboratory(both dry and wet lab) works which include from sample extraction, preparation and further processes and the work includes (biochemistry, molecular biology, genetics, microbiology, immunology, etc.) whereas Bioinformatics is related to dry laboratory work where you use the biotechnology samples and analyse them using the software.
Both are inter related, and the process would be biotechnological work followed by bioinformatics and also many times certain samples directly used in bioinformatic analysis.

At present, the scientific, analytical and problem-solving skills developed by microbiology graduates are high in demand by employers. There are various options available to you after studying for a microbiology degree. You can choose to stay in education & do a Master's degree or Ph.D. in microbiology. Whether you can decide to enter the job market after graduation degree. You can work in both governments as well as in private sectors. Microbiologists are mostly demanded in the UK, US, France, Australia, and Germany. With a degree in microbiology, you can get opportunities in various fields like healthcare organizations, forensic Science laboratories, environmental organizations, higher education institutions, food and drink, publicly funded research organizations, pharmaceuticals and many other industries.
