【深度思考】程序员35岁真的是分水岭吗
作者:互联网
# 准备好套路
**①自我介绍:**千万不能筐瓢,一定要牢记,自然流畅地介绍自己的学习经历、工作经历、项目经历、个人优势等等;
**②抽象概念:**当面试官问你是如何理解多线程的时候,你要知道从定义、来源、实现、问题、优化、应用方面系统性地回答;
**③项目强化:**必须针对简历中的两个以上的项目,形成包括【架构和实现细节】,【正常流程和异常流程的处理】,【难点+坑+复盘优化】三位一体的组合拳;
**④压力练习:**面试紧张难免,尤其是面试这种大公司,可能会严重影响发挥,建议多面一些有把握的公司,训练自己的心态,也可以通过平时多找机会参与交流分享,或找人做压力面试来改善;
**⑤表达能力:**表达能力在面试中非常重要,表达不好非常容易拉低面试官的印象,面试时应该简练、自然顺畅地将答案告诉面试官;
**⑥重点针对:**面试官会针对简历提问,所以请针对简历上写的所有技术点进行重点准备。
