Where are you in France? There is basically two kind of salary in France: Paris vs everywhere else. In Paris area, 2k/month for a junior fresh from school is not a lot. 2,5k is more common. After 2 years, you should be able to reach 3k/month. I am in this case and I currently earn 3,2k/month (.NET house fullstack job).

My main advice is to know that the market wants you. You are in very sweet spot. Always ask more and be ready to bluff an alternative if needed.

My second advice is to always be "à l'écoute du marché". Be ready to switch if something really nice show up. You can go to an interview even if you think you are not going to change. Take the 'propal'.

My last advice is to be willing to switch. I read somewhere that most developer got a better raise by getting a new job. In my own experience, it is true.

Finally if you find a really sweet job, maybe you should keep it. Even if you could earn more somewhere else. Big bucks is useful to pay your debts, but at 3k you should be able to have a peaceful life in France. Enjoy your stay.

Edit: We are talking about "net" salary here without bonus or shenanigans.

Edit2: Yes we hire (like everybody). (C#, F#, Typescript, React, SQL)
