35岁危机已成过去？

今天去西二旗租房，和2手房东聊了很久。我觉得，想了解当下整个互联网的大环境，最好的选择是直接问互联网宝地的二手房东。和我对接的二手房东手下有160多套房子，他对西二旗的互联网的整体情况有着最直观的感受。他说，互联网今非昔比了，10几年前，和他同一批毕业的大学生不管什么专业都能轻松的进入互联网厂；7、8年前，在互联网宝地租房的人一般都能租个3、4年，因为人有惰性不太愿意挪窝，搬走了大概率是跳槽了；但最近几年，很多人只住了一年多就不租了，问他们是怎么回事，一部分是跳槽，一部分是被裁员了，尤其是小米和少部分网易的不到一年就被裁了，感觉招进来就是为了要补贴（这是房东原话，雷总别给我发绿尸涵），快手百度...

电牛小子_：绷不住，这中介操作和我遇到的一样，建议大篮子好好看看合同，不清楚地方问明白，后续跟你对接的大概率不是这个中介
