本屌比较郁闷，被Tesla,Western Digital, Maxim, Arecont Vision几个公司在第一轮
电面给灭了。今天刚刚面完LSI，心情无比沉重。为攒人品，愿意分享失败的经历。
首先介绍本人背景，EE的ms在读，5月份毕业。EE学的比较杂，embedded+analog+
control+power都有涉猎。目前主要着重在embedded领域就业。
今天下午刚刚面的LSI，所以印象比较深刻，就从这里说起 。职位是Application
Engineer，一个老印口音极重。问的问题有5个方面。
1. Digital Logic.
How to implement inverse gate from NAND?
How to implement inverse gate from NOR?
How many sel lines for a 100 input multiplexer?
Describe D flip flop.
2. Analog.
What is impedance?
What is impedance mismatch? How to avoid?
As frequency increase, what will impedance will go?
3. C programming.
Sort an array.
Convert a digit into binary and give the output of number of 1s.
W Linklist.
4. Computer achitecture
Describe what CPU is doing when an interrupt was taken in place.
Describe CPU cache.
5. Instruments.
Logic analyzer, how to use it. How to use ground lines? Color order.
Scope. When measure a critical impedance, why the scope impedance is very
important and how to select?
感觉自己的analog，instruments, C programming 答得还可以，digital听不懂他的D
flip flop所以没反应,Computer achitecture就比较糟糕了，毕竟没学过相应的课。
感觉自己简历比自己本人牛得多，自己太水了，毕竟是半路出家的。很多基础知识不够
牢固。以后需要加强操作系统，计算机原理，数据结构和C语言的基础知识了。
等自己心情好些的时候再发其他几个公司的面经。
