Desventajas
Small company so experience varies widely based on your manager. If you're under an insecure one, which most are because senior management can be abusive to staff, it's not an enjoyable or productive environment. Rules are many and colleagues can be catty. Mostly behind your back if you're lucky. All of this is tolerated by senior management. Unproductive, incompetent people are left in place. I would recommend as a jump start if you're fresh out of school only.
