老中刷题露馅了

楼主 (未名空间)

In a recent interview I asked for LC medium (slightly harder if you actually want to get the most optimal solution).

The candidate proceeded to give the most optimal solution in no time. The
code was perfect. ( it fact it passed all LC test cases upon execution after the interview)

No acknowledgement of having seen the problem before (and I didn’t ask
either).

I asked a follow up to provide a straightforward recursive solution and the candidate could not come up with it.

I asked the candidates thought process on how he/she arrived at the solution. Only repeated the recurrence (dP). When asked how you came up with the
recurrence I got a generic canned answer “oh we build on smaller problems”.

I gave the candidate a strong no hire. The position does not require a fast coder, but does require someone with critical thinking skills. This
candidate did not demonstrate that at all.

能背最优解,多半还是得先理解最优解的,至少先理解了再背要容易很多。背也是背逻辑,不可能一行行背代码。Naive方法出不来很正常。很多时候最优解很难想到,但是
一旦知道了就恍然大悟很好记代码也很好写,反倒是Naive方法常常需要排列枚举啥的

那得是机器人才能不理解还能把Code背对。写程序比写数学题证明还得严谨,错一点都不行。就算Interviewer不那么严格要求,但是人写程序犯的正常错误,跟死记硬背出
一点差错犯的错误类型完全不同,前者没啥大不了的,后者在人看来非常傻逼,因为逻辑根本不通。没懂就抄作业很容易被老师看出来,一个道理。
