According to me, France will be a better option because of the quality of knowledge, teaching methods and various other education related benefits. This country is one of the top countries of European Union, in terms of food, education, tourism, etc. Therefore, if money is not an issue, which I think is not an issue for you, then France is the best option but coming to part-time jobs and working along with studies, it depends on the Visa and permissions related to it. If you have a proper visa and you have the permission to work along with studies then there will be no problem. The problem is that different universities and different countries give different permissions and type of visa to the students.

Hello,
Technical skill does not mean mugging up physics, chemistry and maths. Even the people who do not have engineering degrees also possess technical skills, it means that the ability of a person to cope up with technology and the ability to handle it, nowadays even primary school kids have smartphones and they know their system better than adults, so this is their technical skill.
Yes, MBA will be a better option for you because management is a very versatile, lucrative and interesting field, but the most important thing is your interest and dedication, wherever you put your interest, dedication and will power combined.
If you have no interest in doing M.Tech then surely choose MBA but from a Tier 1 or Tier 2 institution, so that atleast you can enjoy the real benefits of MBA, and education quality in these institutions will be much better from those of others.
