Thinking you're going to work for Google after reading English articles, is really harmful when the closest FAANG office is thousands of miles away in another country.
I am from minor city in Europe, with no FAANG presence, but I found another company with similar engineering first principles. Nobody cares about education and promotions are fully merit based.
NVM you are from France, right?
You really don't have any such companies?
You're extremely lucky to have found a good opportunity in a good company. I will guess back that you live in a major metro area.
France has very little tech industry for many reasons that would be too long to cover. Even the largest national companies that need technology do not hire. If you're familiar with the myth that it's impossible to fire in France, in short that's true, once you have a job it's for life. One consequence is that no company is open to hiring, they only resort to staffing/outsourcing agencies.
