My Facebook Interview Saga

The following is a retelling of the interview process I underwent with Facebook at 1/April/2010 for a Software Engineer position. I didn't get the job. It was my first interview process I have ever gone through and, despite reading all the other interview recaps others have written about companies like Amazon, Microsoft, or Google, I wasn't quite prepared. In any case, I hope the following is useful to others who may be preparing for the whole job game. Note: I've been careful to leave anything sensitive out of this entry for NDA purposes.


2010-March-23: Derek (Technical Sourcer at Facebook) contacted me by email:




Then i replied:




Then we added each other at google talk and here was the chat:

2 - 1499 - 1499.txt

1.韩国学者认为：孙悟空其实是韩国神仙，因为他用的是棒子！

2. 再一次祝福那些借网络发泄的朋友们：握紧手中的中华铅笔，一往情深注视笔杆上的字：2B！
3. 把寂寞刻在酒瓶子上，喝进膀胱里，尿出来，让寂寞洒满一地！
4. 用7%耕地养活占世界22%人口根本不算什么成就。看看日本，用世界1.5%的人口产出了世界90%的毛片才叫牛B。
5. 我凝视你地眼睛 发现了深黑色的寂寞,你说那是因为夜太短.你凝视我的眼睛, 发现了火红的刺么忽,我说那是因为睡电褥子睡地——上火....
6. 生活中，每个人都是演员，而装B的人只是其中的佼佼者
7. 一晚上旳髙潮,怎么满足生活旳低潮.
8. 我喜欢闷骚女人。在别人面前闷。在我面前骚。
9. 我学会了喝酒，是想把寂寞和悲伤给淹没，没想到，他们他妈学会了游泳....

3 - Windows Scripting - 2008-12-19_02.11AM.html

Power of windows command shell

I managed to use just pure windows command shell scripting to process around 500M text data ....
pure means not external exe/com files needed,,, just windows built-in commands (e.g. for, call, if ... )
amazing,,, windows scripting (*.bat, *.cmd) can just do almost anything... it is as powerful as linux shell script...

ok ,, here is the task....
there is a csv file,, let's say A.csv, which contains something like this...
1 5 2 18 0 24 18 0 54
2 5 3 18 1 14 18 1 44

5 - Spectrum Master - 2008-12-10_13.59PM.html

Spectrum Master
I got to play around with this machine these days... Spectrum Master MS2721B, MS2723B, MS2724B....



When I finished the measurements,,, i had to copy around 100M data from the SM to USB stick.
anyway, it took longer than i expect (maybe it does not support USB2.0 transfer)...

Why not use FTP??? I tried,,, and i couldn't login... i couldn't find access details on the manual or internet ..
What the hell is the account name and password to login to vxWorkds 5 ftp?

6 - Autorun.inf Virus Protection - 2008-12-2_07.36AM.html


A startup script to enable autorun.inf virus protection
Some virus create autorun.inf file to enable automatic file execution when you browse the folder,, which is very annoying... you can create a folder with the same name and in this case the virus would have trouble to write to that file. "Autorun.inf" even can not be overwritten because it is a folder...
Put the script at the startup to make sure every drive has a hidden folder "autorun.inf"

@echo off
REM A Batch Script to Create Folder 'autorun.inf'
REM This can prevent autorun.inf virus.
REM Free to use, put at startup recommended.

8 - A Story - 2008-10-11_03.27AM.html

似乎很久没有更新这里的日志了。
转一个小故事。
=============

一只小猪、一只绵羊和一头乳牛，被关在同一个畜栏里。有一次，牧人捉住小猪，他大声号叫，猛烈地抗拒。绵羊和乳牛讨厌它的号叫，便说：“他常常捉我们，我们并不大呼小叫。”小猪听了回答道：“捉你们和捉我完全是两回事，他捉你们，只是要你们的毛和乳汁，但是捉住我，却是要我的命呢！”

立场不同、所处环境不同的人，很难了解对方的感受；因此对别人的失意、挫折、伤痛，不宜幸灾乐祸，而应要有关怀、了解的心情。要有宽容的心！
