Vantaggi
SYSTRA is a world leading company in transport planning and engineering. This french company, owned by the RATP (paris transports company) and SNCF (french railways) is present in most of the countries in the world. You can start you carrier here after your degree, as an engineer in a diversity of jobs: transport planning, structures engineer, railway, catenary... Then, 4 or 5 years after your arrival, you can evolve to a project manager or an expert. Long projects usually take 2 or 3 years, people is normaly working on the building site if they are surveying the construction, or at SYSTRA offices somewhere in the world to make the construction project. SYSTRA and his subsidiaries (SYSTRA Consulting and MVA) have offices all around the world, mostly in Asia and north Africa, the engineers are usually local. I think is a great place to start a career and to learn a lot.
Svantaggi
This is a company of transports engineering, so if you are looking for this, this is really the good place. However, you evolution will not be very fast (this is a big company, 3 000 people, so evolution is slow although you emigrate to one of the local offices). Management is done mostly by engineers who are in the company since a long time, so it's not always great.
