The publication QS Top Universities has raised some points that you should evaluate before starting to choose a master. We anticipate some of them:
Are you sure about the field in which you want to acquire? Do not forget the passion for the subject, the motivation for studying is essencial. Have you thought about studying abroad? If the curriculum raises student exchange or study trips, the experience can be much more rewarding. On the duration of the master, companies value that have dedicated between 1 year and 14 months.
Obviously that will be your skills and knowledge what is going to help you get the job of your dreams, but given the competition, studying a Master will give a push toward your goal.
