You haven't said what you do, software testing or development? Softcom is not bad for freshmen. You can learn a lot by joining a good project team. The salary is relatively acceptable for graduates, but the benefits are less. Graduates can consider changing jobs during Softsoft exercise until they feel good. If you have experience, you can play a key role in the project team, or go abroad to Japan, South Korea or Europe and America. Otherwise, I still don't think iSoftStone is necessary. I am now doing embedded development in Wuxi Softcom and will graduate soon. I think I learned a lot. If you do the test, the technical content will not be too high.
As for the interview, the interview will be a little more difficult, and the exam will not be too difficult, but English is the foundation. It is best to prepare an English self-introduction.
