Hi
I am applying for HEC Paris MBA
I am an Indian and have 5 years of IT experience.

How are the job opportunities in France and EU. I have heard that jobs are not very good these days.

what are the visa norms, How long after graduation can I stay in Paris. Also, I am taking my Wife with me, can she do any part time job on Dependent visa?

I am looking for a career change, Is it difficult with my profile to move into finance or Consulting.

What is the cost of living over there. how much expense one will spend when one stays with family over there?

You can find answers to a lot of this on the HEC website. Why not see what you can find for yourself and come back with more specific questions?

Seriously, I'm sure most of this info is readily accessible on the school's website.

One major thing is going to be the language. If you are planning on settling in France long-term, your ability to land good jobs will come down to how well you speak French.

And Paris is fairly expensive, for some things you are going to pay more than you would London, although rents do tend to be less than in London. If you are not too risk-adverse you could always move out into the Parisian suburbs but I am guessing this will be a bit trick with a family. Keep in mind that HEC Paris is not actually in Paris but outside of it, and as such, many students choose to live on-campus.
