Avantages
brand name. This is global company so encourages you to travel and work in other locations to understand their culture. They have very strong culture and influence. They run company pretty much flat structure, open culture and encouraging innovation. They also allow you to travel. Big pocket book with the company. They have many product line, so if one bores you then you have plenty of other new technologies to work on. Different positions are also available. They tend not to lay off people very easily, so it is kinda secure. They are pretty good at moving projects internally.
Inconvénients
this place was previously entrisphere. bought by ericsson. so it lacks ericsson culture. No respect for individual people's work. The CEO of entrisphere says that its no sacrifice that employees have to come on weekend, long weekends and holidays to work. Really demotivation for all. Since it is european company, there is no stock options. Their ESPP is pretty lame. Like other european companies, the bonus is pretty lame. Since it is more of an socialist kind of structure, so they share the profit no matter how hard work you do during the year. Overall I recommend you to join American company.
