Vantaggi
Quite frankly, the only pro is that they will hire almost anybody, so if you have just landed to the Netherlands and you absolutely need to find a job, they will provide one for you, albeit with the lowest salary available in the country.
Svantaggi
The salary is extremely low, the management is extremely lame. The only way to make a career to make facebook friends with the management which, in turn, suffers by an absolute lack of preparation whatsoever. The environment is extremely stressful, they try to squeeze every possible drop of life from you without providing the necessary tools. There is no investment on the customer care department, there is no training, they do not improve your knowledge in any way. There are a lot of actual and former employees with legal issues with the company, even when you finally earn (by law, after the 3rd renewal) a permanent contract, they do not hesitate to fire you or to put you in the condition to resign, which is of course illegal. Proof of it is the number of legal actions that Booking.com lost against former employees in the last years, and counting. Furthermore, working here doesn't improve your CV, everybody in the Netherlands knows that this company does not add anything to your previous experience. There is no way to stimulate your creativity, actually whenever you try to come out with something new you are pushed away by the laziest management I have ever seen. Everybody's level of incompetency is upsetting. I have been lucky enough to find another job, and I will not look back at them anymore.
