The good things
It really depends on the project that you will be put into. Some projects are well structured, but there are also projects that are not that organized, but it is not a bad thing, it is just more stressful but you will have additional experience.
Again, it really depends on the project. There are projects that you will have a lot to learn thereby increasing your career growth but there are also projects that are stagnant, you will feel that your career is not growing at some point.
