今天读了这篇文章How to Interview an Engineer for your Startup，看了看人家大牛如何面试Engineer，学习了不少。

其实关于link shortener，本来也有思考过一些。不过确实没有像此文思考如此之细。尤其关于数据库优化方面是我软肋，更是无法了解如此之多。

也不仅单是这个case吧，也不仅单是服务器、数据库或者网站吧。总归一个好的Engineer应该随时把握着开发-性能-质量-产品周期，把事情做到最好。要不断历练自己。

复制原文红字自勉吧：
These days, people that can cross between frontend, backend and design are the true rockstars and exactly what we’re looking for, so I like to get a feel for whether they “just like to code requirements” or they can truly get proactive and help us build product.

做个工程师还有不少路要走。
