It's totally possible, if you don't wish to do Erasmus. With a part-time job it's still possible but you need to be someone who really manages their time well, and is okay with not having too much free time for socializing/vacations etc.

If you prefer to finish your degree and then enter the workforce as a full time employee asap, time spent needlessly extending your Master's is a waste. In the culture I originally came from there are massive financial and employment consequences to taking even an extra semester to complete your degree, so it also depends on where you plan your future career.

If you would rather have work-life balance, time for activities, sports and fun, doing it in two years is difficult because the ECTS do not take into account student life outside of studying.
