篇5:德尔福笔试心得

德尔福笔试心得

在作德尔福的笔试卷子时,我就是因为专业问题要用英语回答而提前离场的,而坚持到最后的师兄终于获得了offer,专业知识准备更加复杂,对于研发技术岗的笔试要求都比较高,我在这个方面基本没有准备,自信的认为自己凭借先前的积累可以应付一二,哪知第一次笔试后彻底失去信心,于是打算复习模电数电和其他知识。然而,模拟电路直到考完所有笔试后才勉强看完一遍,而此时前面看过的早已忘记,这也是我准备过的唯一的专业知识,其他的到现在也没有开始。对于这些笔试,细节很重要,即便你每天都在使用,但是却不一定能够答题,因此,提前一段时间复习一遍才能轻松的应付笔试,避免首轮就被淘汰。

对于笔试中的逻辑测试和智力测试,本来于我们而言都不是什么问题,但是却有熟练程度的差别,像威盛那道猫捉老鼠的题我想了整个考试时间的三分之一,而如果知道思路的话却用不了两分钟,

这些东西不需要特别的`准备,因为你也不知道他究竟会出现什么类型,但是却又不能过于大意,我最初也不以为然,但每次考完的差距却让自己不得不多加训练,于是到网上搜索各种各样的智力测试,在饭后茶余和同学一起思考,然后找到规律,应付考试。对于一些性格测试,我始终持怀疑态度,我认为他们不在于选拔人才,而在于抽签式的过滤掉过多的应聘者,其中的规律,我始终不得而知。

以上是我面试德尔福笔试回来写下的心得,可能写得不怎么样,但句句都是肺腑之言。

篇6:德尔福笔试心经

德尔福笔试心经

今天早早的过去深航,里面已经坐了五六个同学了,一经交谈,哇塞,三个是我们学校的。华农人就是强!然后很巧的碰上了小哲的同宿舍森。

过了不多久就开始笔试了。今天的笔试比较多考的营销方面的知识,开始的客观题还好,基本上不会的话也可以猜出来的。但是到了主观题就比较难了,比如问一些渠道的设计方面,只能乱吹。到了最后一题讲市场调查的,还好我之前刚好看了一本市场调查手册,里面非常详细的`讲了第一手资料的收集。然后我就大吹特吹。

我和森是最早交卷的。出来后我和他在聊天,又是一个强人,很有自己的想法,对市场营销方面颇有研究,呵~~以后可以多请教他了,

他介绍了我去看两本书《困境与出路》以及另外一本营销类书籍。回去的路上和森一直谈,聊了很多,多数是他给我介绍一些国外的先进的营销案例。

总的来说,森是个很不错的人,比较诚恳,很有自己的见地。只是有点不够自信。森,其实有些事是我们无力去改变的,我们只有接受。可是我们的态度却是可以改变的。对自己再自信点吧。你是个很强的人。加油~

明天有个招聘会,里面有家上海航空,听师姐说里面待遇很诱人。刚好我也要去中大笔试,行!就过去看看!
