请问拿到Amazon offer的都分好组了吗？

offer的邮件是这么说的：

You will be assigned your sub-team and your project on your first day. There is nothing specific to prepare for day one. All interns will be assigned a Manager and Mentor to support their development.  Also, all interns will be expected to complete an assigned project and learn new technologies, programming languages, and systems.  At the end of your internship you will receive a hiring decision from Amazon regarding a return offer. We will then work with you on your team and location preferences and try to find the best fit for continuing your Amazon career.


我看到地里面很多人报自己的组，想请教一下大家，有人跟我情况一样没有组吗？有人知道为什么吗？


非常感谢
