Pros
Was working in Corporate located in Belgium. In the beginning there was an international atmosphere with a lot of employers, trainees, VIE's from India, Germany, USA, Brazil, Bulgaria, China, Vietnam, Poland, Spain, Greece. Since 2014 company focussed more on French speaking profiles. Lhoist is a familial company that don't count for internal event to prepare, so it's quite nice and often that you can meet and know your new colleagues.
Cons
Excluding the car, it's very difficult to come work by public transport, in plus the train(s), you need to take a local bus which stops the service at 9.10am and 6pm, or even not exist in other location of Lhoist, so you need to walk. As for company cars, not all employers have rights to have one, so I advice you to ask it before. For the strike days, you have to take day off. It's very difficult to have permanent contract.
