J'ai travaillé chez Infinity Ward en Contrat Permanent
Salary, daily great free lunch (and dinner when working overtime, which is pretty much all the time but varies from department to department, and bonus.
Don't look to HR for any kind of help. Longest hours I've experienced. Large company so some leads better qualified than others. Culture that rewards dishonesty, bullying and more.
Conseils à la direction
Listen to your developer's complaints and take them seriously.
