Hi there and congratulations on figuring out the forum structure 👍
I would say that there is a very very very large number of masters programs that have multiplied in the recent years. Usually the biggest recommendation and perhaps the best one is to pick the best rated as they have the best likelihood of providing a positive employment outcome at the end, though there is no guarantee as you probably know.
However, the strongest names tend to attract traditional employers and especially some of the industries you have identified.
Usually they will take GMAT or GRE so you can take either one. The higher the score you can get, the better at your chances of admission and potentially a scholarship.
My suggestion is also to apply in countries where the native language is English because you will have trouble recruiting unless you speak French or German or Spanish. So I would focus on the UK or US with exception of a few French programs which are fairly strong.
Getting a job after graduation is a big journey. First you need to get a great score and then find good programs that fit your needs and then apply and then get in and then secure an interview for a job and then nailed that interview. If you are traditionally terrible at interviewing, that’s going to be big area to watch out for and improve even before you go to school because there will be a lot of competition for good jobs and the best candidates with the best interviews will get through .
