The team was very good.
People were very friendly.
Located downtown, close to everything.
The building is nice.
International team, no hostility towards non-French speakers.
The environment however is noisy (at some places), people who have to talk and call each other as part of their jobs should not be placed near software developers who need a more quiet environment to think and write software.
Also, too much restrictions on everything (for security reasons). Not possible to download and install your favorite software tools, not even those open source and free ones.
