It must be noted that you must have a master's degree to apply for Nordic PhD. The implication is that you must graduate with a master's degree certificate when applying. Since PhD is regarded as a position, it is necessary for employees to hold the required degree.
Language requirements
You can't speak Danish, Swedish, Norwegian or Finnish, but you must know some English. Although English is not the official language of the Nordic countries, the English level of the people in the Nordic countries is still quite good, and it is no problem to deal with daily life and study and research in English. However, learning the local language can help you adapt and integrate into local life quickly.
As far as the language proficiency test is concerned, both TOEFL and IELTS are accepted. The minimum requirements for TOEFL or IELTS can be found in the specific job description. If you mainly apply for a doctorate in northern Europe or Europe, IELTS can cover the applications of most schools in Europe.
? A cover letter?
Doctor is a job in northern Europe, so it is one of the necessities for you to find a job. The cover letter is one of the things you need to pay attention to, and its function is similar to the personal statement or purpose statement required by the British and Australian applications in North America. But the form is similar to a magnetic letter, which needs to reflect personal information, research interest in job matching, research ability and desire for jobs in relatively short words.
? research project
Each post will have a corresponding project or topic introduction, and what kind of ideas and implementation plans you have for a given topic will also be the focus of tutor recruitment. Then specific ideas and plans should be reflected through research proposals. However, because the duration of each job information release is not necessarily (the explanation will say that the application is closed), you need to make a qualified research proposal within a given time.
? Other requirements
Academic degree certificates, transcripts, resumes, letters of recommendation (or referees) and other materials are classified as other materials here because these materials are similar in all degree applications around the world, so I won't repeat them here.
