Air France has a very large customer care center in Prague, so at the very least, you are guaranteed a job there even without speaking any Czech or having an education. They pretty much instantly hire all French people they can.

As a foreigner living in Czechia, I am quite fond of the country. It’s great. People are fun and have a dark and sarcastic sense of humor (my type), and the food and alcohol are all excellent. However, bureaucracy is nightmarish here.

I have never been to any of the other countries you have mentioned, though.

I think it depends a lot too on your career and where do you see yourself in the next few years.
