MS: Do you know C++?

Me: Yup.

MS: Tell me what is memory leakage.

Me: Blarblar…

MS: Right. Then what operation would cause that leakage in C++?

Me: Blarblar…

MS: Right. You know JAVA?

Me: Just some introductory courses.

MS: OK, tell me about memory leakage in JAVA.

Me: Blarblar…

MS: Right. Do you know the name of that recycling mechanism?

Me: …（忘了）

MS: Let's get back to C++. Do you know what virtual function is?

Me: Blarblar…

MS: Good, then what is polymorphism?

Me: （从大一学过C++之后就没怎么写过程序，我怎么讲得清楚多态。。。）支支吾吾讲了
一点，说是继承里面的内容云云。。。

MS: Alright. Let's move to data structure. Did you have that course?

Me: Yup.

MS: What data structures did you learn?

Me: Queues, stacks, …

MS: What's the difference between queues and stacks?

Me: FIFO and LIFO, blarblar…

MS: Right, any more data structures?

Me: Tree…（我想了想没说Graph，如果问起graph来不是要被问死的啊）

MS: What trees?

Me: Binary tree, Octree, blarblar…

MS: When do you use binary tree?

Me: （卡了一下，我n年没碰这个了同学！）In haffman coding, blarblar… （幸好在
我微茫的记忆中有-_-b）

MS: Good, that's right. Then do you know hash table?

Me: （我傻掉，这个东西老师当时只是讲了用途，没有讲实现呀。。。）It's something
used in searching within a large data structure…I do not quite sure about t
he implementation…blarblar…

MS: OK. Now I give you an example: I want to implement a dictionary. Which dat
a structures would you use?

（此处省略细节无数，就是用hash table之类的，把我问伤掉了）

MS: Did you have any algorithm courses?

Me: No. （我们专业没这门课。。。）

MS: (Surprised) Well, do you know any sortting algorithms?

Me: （你还一定要我讲算法啊）Well, my instructor of C++ once mentioned Bubble a
lgorithm （其他算法不敢多讲，怕要我描述，这个东西用英文讲太难了）

MS: Please describe it. （还好没多讲。。。）

Me: Blarblar…

MS: That's right. What's the time complexity of bubble?

Me: (忘了是O(n)还是O(n2)了。。。只能很诚实地说我忘了，还是不要跟投行吹牛的好）

MS: That's alright. Then when will you use Bubble?

Me: Only when the element count is not too large coz I seem to remember that t
he time complexity is not small. （说着这句话我自己都汗一滴）

MS: Right, the time complexity is O(n2). Then let's move to database.

Me: OK (累死了）

（此处再次省略无数细节）

MS: Our technical question ends here. And there will be some general questions
for you.

Me: Fine.

MS: Do you know what do we IT dept do in Morgan Stanley? Why you applied to th
e job?

Me: Blarblar… （说句实话我还真不晓得投行的IT是干嘛的，后来听说是纯R&D，再汗一
个。后面就狂拍MS的mp，说他是industry leader with world's top talents云云。。。
）

MS: Do you have any relevant working experience?

Me: Blarblar…

后面就是Thanks for your time and effort, we will inform you soon if there is a
ny news之类的话了。挂机，半小时（我的手机费。。。）

我觉得Morgan Stanley的IT要求还是很高的，我自己掂量一下估计是定然被bs的。我觉得
要电面的话英文一定要好（我自己觉得我英文还过得去，不过用英文将技术的东西就是另
外一个故事了），然后编程语言、数据结构、算法、数据库等东西的细节要多了解，MS的
问题是蛮细致的。最后我觉得要进这样的公司要靠rp的，所以不要多想，just enjoy it.
