google内推rej

今天收到rej, 申请的是SDE intern。回复为 The preferred requirements of the role include programming experience in one or more of the following languages: C, C++, Java and/or Python, experience in systems software or algorithms, familiarity with TCP/IP and network programming, and knowledge of UNIX/Linux or Windows environments and APIs.

请问地里的小伙伴，如果简历上已经列了以上几种语言和系统、bash经验仍然被rej，应该怎么办呢？继续改简历还是现在开始折腾网课？本来打算挤时间学一些mobile dev或是js做个toy project的，现在有点被打乱计划了。另外请教大家求职期对时间的安排，谢谢。祝大家offer多多。
