我申请的Senior Software Developer, 电话那边听口音是两个老印， 感觉还可以，但
一个小时后就接到拒信了，不爽。 很多东西是open discussion, 我并不觉的这样的
interview真的说明什么，anyway, 下面是一些问到的题目，回馈版面吧。
1. C/C++ difference, Why use C++?
1.1）讲到polymorphism后，让举一个实际的例子，工作中用到的。。。
1.2）能不能用C来实现polymorphism，怎样实现，也答了
1.3）C++是如何事先polymorphism的，说是virtual function table, 问VFT存在哪里？
1.4）polymorphism的pro and cons, especially cons...
2. design web server to handle thousands of request per minute.
3. pro and cons between threads and processes
4. what is memory leak, how do you prevent memory leak, how do you design a
way to detect memory leak...
5. what is mutex, how os implement mutex?
6. what is deadlock, then design a way to detect unlocked mutex.
