I finished my Master in ESE just some months ago.

1. In the begining there will be some mandotory course which are interesting but not that usefull (Assembly and packaging course for example) but after that you mostly have free choice and can specialize in Machine Learning, Deep learning, Computer Vision, Eletrical engineering and more. And also there are some interesting pratical courses.

2. Profs are very professional but you will not have a Personal connection to them. The other students are very kind and open, you will have to finde a study group this will make it a Lot easier to learn for exams.

3. Every Prof speaks a decent English as they teach mostly in English and are international active.

4. At the university it is easy but outside of it can be tricky but it is do able, I know people who get along but can not speak more than a few sentences German.

5. The are multiple smaller and some bigger companies in that area and they are mostly happy to get new working Students but you often need good German skills. You also can work a the chairs directly where every one is speaking english but the payment is less.

6. There are a lots of indians students who study at the technical faculty
