My main advice in determining which master is right for you is simple; look back at the courses you have had so far and especially at the ones where you really enjoyed working on and where you ended up doing more than was required.
My advice to students would therefore be not to have a fixed mindset about what different careers entail, but to try it out for yourself, for example through open days and internships.
During my in Delft I noticed that I liked the field of Data Science. Not only the math and algorithms in this field are beautiful, but also the dozens of applications.

As a special project I got to work on an expert system to control the Oosterschelde storm surge barrier. My time in Delft was really enjoyable in all aspects.
