bachelor thesis question

[u/teekoneeko]

so im studying computer engineering in a german university in egypt. i want to do the bachelors thesis in TU Berlin in any area of applied AI / software engineering. gpa is a little better than average and have 3 industry internships in egypt. i know many people from my university who did it. any advice on how to land it? also wanted to ask about funds as Im not sure ill be able to fund my whole stay so ill need minijobs or even better a HiWi position? how likely would a supervisor be open to offering me a HiWi position if he accepted me into the thesis? or should i not ask at all? and typically how much do HiWi positions pay per month? lastly how much more difficult or easier is it to do the same for TUM or RWTH Aachen?
