不会写code的就不行了

发帖数: 2911 | 4 这叫开门见山，直入主题。现在不少电面也是这样的。
主要是他们不想你只会纸上谈兵，眼高手低。很多时候你知道原理和算法，实际去写代
码不一定能写对，或者对边界情况考虑不周全。
有个著名的例子是，在早期的计算机编程年代，第一个二分查找的算法被提出后，过了
十多年，才有人发表了几乎没有bug的二分查找代码。 |

发帖数: 1293 | 6 没有看Programming Pearls了吧，看了你就知道了
不过我也有点怀疑，按道理来说发表binary search的那篇paper
里面就会有接近实际代码的伪码的了
里面的证明要verify这个code的正确性，就需要用到啥循环的
pre-condition, post-condition，和loop invariant的

they are designed for fresh graduates without any experience.
in practice, if some algorithm is needed,that's weeks, months, or years of
work, not 15 minutes work.

One example is, go ahead and try difficult problem in topcoder or google
code jam. Those big Niu can solve them within an hour. It could took me more
than a few days, if I could find a solution myself...

if you can consistently do that for most of 1000 problem, you are really
very niu.

div1的1000分题我最多会做四分之一，耗时也要两小时左右。

that's why i'm really pissed off
but if these stupid suckers love writing binsearch on white board, then
I can do it, I can train myself to excel in these stupid questions,
as everyone knows, after u write all the answers for Programming pearls,
you will be fluent at these
but these are completely useless in work, nor do they show ur potential
to solve real problems at work.
real problems at work require persistence, fast learning ability,
and problem solving ability.
so now I highly que

发帖数: 4965 | 15 point is, the interview questions are much much stupider and simpler
than the code jam questions.
yes code jam winners can finish the interview questions immediately,
but answering the interview questions does not show any linkage to ability
to win a code jam

发帖数: 1663 | 16 the point is they don't expect you to write all the answers for programming
pearls before you go to an interview. this kind of interview is designed to
test coding ability and basic algorithm. and the fact is, those suckers you
mentioned who rules at acm or codejam or topcoder, turned out to be outstand
ing as well in practice.
