求职信息-求鉴别

收到下面信息，不知道是不是卖课的？ 还是华人团结相互帮助的，求鉴别。。。

How's everything going on? I along with several other managers from top internet companies are running a Wechat group that help job seekers and young professionals connect with hiring managers directly. In this group, you will have access to first-hand industry experience, weekly live webinars host by managers, and free interview tips. You can even ask managers for mock interviews, skills training and even long term mentorship.

One of my colleague in Google is the admin, his  wechat:  Google_Mingshuo   , he will let you join if you mention your are referred by me.

你好，为了帮助华人同学更好的求职和发展，我们几个科技厂的tech lead组织了一个微信交流群，我们会在群里发一些技术和行业的分享以及一些面试技巧交流，感兴趣可以加入我们。我一个在谷歌的同事是进群的admin，你可以加他微信：Google_Mingshuo  说明是我refer的就好
