I would say that it's exciting and challenging and the infrastructure is top notch. There are also a lot of systems in place to support international students. There are a lot of possibilities for one to advance as a student and as a professional. The courses are not easy and one would require a fair bit of self-discipline.
Course Curriculum :
It is highly research based and the lessons are taught by professors actively involved in the aforementioned research. It is not easy and requires a lot of prerequisite knowledge.
Exams :
I would say that it depends on the subjects taken in your bachelor's degree and your grades. Other than that, IELTS. My score was 8.0 in it. I had to submit a motivation letter outlining my motivation to apply for the course and my future plans. I also submitted a letter of recommendation from a professor and my CV with my academic and professional info in it.
Placement :
There is no placement program however there are a lot of companies and startups in the area that offer opportunities to Microsystems engineers. The university itself offers a lot of further research opportunities.
Internship :
I'm doing a couple of student jobs at a startup and also at a research institute called Fraunhofer ISE. You can expect to earn an average of 13 euros per hour.
Fees :
It's around 1600 euros per semester.
Faculty :
This faculty is quite accommodating to international students and they are generally quite approachable and even quite sociable.
Campus Life :
The infrastructure is top notch and you have access to almost everything you can expect.
Hostel :
It's not easy to find accommodation in Freiburg. The rents range from 250 to 450 for student apartments. The prices have increased recently due to the energy crisis. A personal example; I live in an apartment with 4 people with individual bedrooms, a common kitchen and two bathrooms for 380 euros per month in an apartment complex owned by the student union, which is hard to get.
