The program itself is very challenging, which at times can seem rather discouraging, but in the long term, I think it would be very good for personal and professional growth. However, the professors can seem a bit unapproachable. Many resources are being provided. The university and program are very good for networking since the program works closely with the Max Planck Society. The university is very international, and even though German speaking would be recommended, English works just fine. I would highly recommend my university and program to other people.
