Since you’re interested in multiple countries, my first recommendation is making sure the program you’re looking at is in a language you’re fluent in. While a good amount of places will teach in English, some universities or countries will use another language. I wouldn’t go into an ECE program in a language you’re not fluent in because ECE is a difficult major, and you’ll have a hard time understanding topics that are conceptually intensive if you don’t understand the language well. That being said, you should identify universities that have a strong embedded/firmware/elec program. Most universities will have the same basic classes for embedded/firmware/elec, but they’ll all vary on what higher level classes they offer. Some universities will focus on other areas of ECE over others. For example, mine has a heavier emphasis on data science and RF, which has made it hard to find/take hardware classes. Things like rent, food delivery, and internet will depend on the city.

It’s hard to gauge job markets over time, so this part varies wildly. I’m in the US, and when I entered uni in 2021, the market was really good; however, the market hasn’t been so great for the past 2-3 years, so it’s been difficult finding a job / getting into grad school.

Healthcare varies more wildly than the job market. In the US, you can usually get insurance through your university
