题目不少呀,题挺基础,自己大概看了看,自测了一下,很多概念也了解,但又挺模糊,真要能答全也不容易,也可能是自己基础没打好,呵呵。

很久没上CSDN了,一直加班,好久没上来学习了,自己落后了许多。
|
貌似确实基础了一点
|
怎么全是问答题,english 我喜欢

楼主的开发组貌似是腾讯的?powful
|
基础才是王道

马克

要更专一点就更好了
|
很多都忘了,看来我挣不值12W
|
没仔细看,有些还算基础,但是要全部答出来还是要一定基础的。
|
田伯光现在还是在深圳吧?
|
你的英语水平挺不错的,技术也学得好,向你学习呀。
|
yes
搞些高深莫测 你就牛?显出你能耐?

比较基础,偏于网络。 很多都不知道呢,呵呵。

说实话,深圳年薪12W,整体水平上看,大概也就是中等偏下吧
这考题的对象应该是本科毕业两年以下,研究生毕业一年以下吧,难度应该差不多了。而且如果涉及到专业领域
的深度,只有非常对口的人才能答得令人满意,这样就大大限制了招聘的来源了
而且这份考题看起来简单,但是涉及面很广,如果深究,就未必像看起来那么简单了。
PS:顺便提个小小的comment:
4. You run a program in a terminal, when this terminal disconnected, whether your program will exit or not? Why?
这题即可以是Yes也可以是No,因为有&

这就是那个书托吧?
什么样的职位需要什么样的能力,你要是招一个Area Architect,就需要明显加难度了
这不是显不显的问题,而是你如果招进来的人不能胜任这份工作,最终倒霉的是你自己!

上面这些题目,看似基础,但如果都能很快的答出来,应该也很牛了。
那些说出的题目很基础的人,估计你们都很牛了。
