Pluspunten
One will be exposed to develop world class enterprise applications. There are very few companies that do such a large scale applications. Learn them while you were there. Your hard work is really appreciated by your peers. But don't expect to get any growth. One can grow when you stop working and just do talking. One should learn to play politics. If you just work silently and solve the company problems, no one cares for you and you will stay without any promotions. Keep in mind to negotiate a good starting salary. No one gets a good raise after joining. Company cares about the shareholders rather than employees. So, don't get too much emotional with the company. You are paid for your work "period"
Minpunten
Hardwork or smart people stay at the bottom of the hierarchy. One has to play politics to grow up the ladder.
