自己结合考试经验，总结了一下，希望对大家有帮助。因为有点多，所以没有直接贴过来，上面具体的笔试题都是网上找到的，只是结合自己考试的经验总结了一下，我笔的是技术类的。
IBM笔试题（一）
IBM笔试题
第一部分：IPAT (IPAT 的全称是 Information Processing Aptitude Test)。
PartI 15min 15Ques 矩阵排列
PartII 4min 20Ques 数列猜测
PartIII 5min （不记得多少题）Ques 数学计算
PartIV 15min 15Ques 矩阵排列
每部分单独发卷，卷子第一页是样板题。没说开始考试，不让翻页。
时间到了就收走卷子，但是IPAT的答题卡是在最后所有答完再收。
答题方法，选哪个就在哪个地方画叉，一共有ABCDE五个选项。
题型和网上历年的题目一样，稍后做了一个总结。
记分方法：I和IV打错不扣分，II和III打错倒扣分
第二部分：技术卷，答题时间是一个小时，有ABC三套卷子。
熟悉JAVA的选做AC，熟悉C++的选做BC。
题型为单选和多选，每题分值不同，做错不扣分，多选选不全得一半分。
我答的是BC卷，B卷全考C++，多为读程序选结果，类，字符串，指针之类的。
C卷什么都考，很细，UML、数据结构。。。。。
IPAT总结
1:
E D C B A
C A D E B
A D B C E
B E D A C
D C A E B
Start at the fourth letter of Column 5 and follow the letters around the outside of the pattern in a clockwise direction. What is the second letter between the second E and the second B you come to?
答案：C
解析：根据题意，从第5列第4个字母开始，在矩阵元素外沿顺时针方向走，在第2个E字母和第2个B字母之间的第二个字母应该为C，如图所示：
2:
A B 2 C 3
1 1 B 3 D
A 1 B C 4
5 A 5 2 B
E 5 D 2 C
In the row that has more letters than numbers, in which the numbers are separated by only one letter, and in which the numbers sum to less than the sum of the numbers in the second column, which letter comes just before the second number, counting from right to left?
答案：C
解析：根据题意：（1）字母比数字多的行有第1行、第3行、第5行；（2）数字只被1个字母隔开的行只有第1行；（3）在第1行中，从右往左数，在第2个数字（即2）之前的字母应该为C。
这道题的关键是找出题干中要求的那一行，其中最后一个条件：这一行的数字之和要小于第二列的数字之和（即1+1+5=7）可作为排除第5行的依据。
3:
E D C B A
C A D E B
A D B C E
B E D A C
D C A E B
If Row 4 were reversed, what letter would be above E in Row 5?
答案：E
解析：如果将第4行的字母倒转，则第4行变为：C A D E B，则在第5行字母E的上面的字母就是变化后的低行，从右往左数的第2个字母E。

IBM笔试题（四）
其他IBM IPAT笔试题
三部分
第一部分 看矩阵题 时间15分钟
PartⅠ:
本部分计分方法为答对题数乘以1
给你一个矩阵： ㈠ ㈡ ㈢ ㈣ ㈤
1 a b c d e
2 b c a e d
3 c b e a d
4 c e d b a
5 e d a c b
回答以下问题。
问：⑴将第一行和第四行交换后，第一行第四个字母下面啲左边啲下面啲右
边啲字母係？
①a ②b ③c ④d ⑤e
⑵将所有出现在d左边啲字母从矩阵中删掉。将所有出现在a左边啲c字母
从矩阵中删掉。如果矩阵中剩低啲字母啲种类啲数目大于3，答案为原
矩阵中左上方至右下方对角线上出现两次啲字母。如果矩阵中剩低啲字
母啲种类啲数目小于或者等于3，答案为原矩阵中右上至左下对角线上
出现4次啲字母。
①a ②b ③c ④d ⑤e
P4
⑶将所有啲a用4替换，所有啲d用2替换，边一列啲总和最大？
①㈠ ②㈡ ③㈢ ④㈣ ⑤㈤
⑷从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个
①a ②b ③c ④d ⑤e
⑸沿第5列从上到下，接着沿第3列从下到上，接着沿第4列从上到下，接着
沿第1列从下到上，接着沿第2列从上到下，第一个出现5次啲字母係？
①㈠ ②㈡ ③㈢ ④㈣ ⑤㈤
⑷从左上字母开始，沿顺时针沿矩阵外围，第四次出现啲字母係以下边个
①a ②b ③c ④d ⑤e
⑸沿第5列从上到下，接着沿第3列从下到上，接着沿第4列从上到下，接着
沿第1列从下到上，接着沿第2列从上到下，第一个出现5次啲字母係？
①a ②b ③c ④d ⑤e
（请停止作答，等待提示翻到下一页）
第二部分：英文字母排序 时间25
个人心得：先把26个字母写一排在纸上，容易找规律些。可惜做到一半采用此法。
题信大至是：aabbcc 选下一个为d。当然有的不这么简单，有时跳了好多个，也有向前
或向后跳着的规律。所以先把26个字母写一排在纸上，容易找归率些。
第三部分：数学题时间35
繁琐的数学，最好不用计算器（只用了两次计算器），大致估算就可，这样节约时间
可惜还是没做完。

====================
1.有3台复印机（copier），平均每台每周工作42小时，每台每周最少工作35小时，问一
台复印机每周最多会工作多少小时？
42*3 - 35*2 ＝56
2.在一个长11 meters，宽6 meters的房间里，铺上10 centimeters厚的水泥，问需要多
少水泥？
11*6*0.1＝6.6 cubic meters
3.某公司有两座办公楼，一天，第一座楼20％的复印机和第二座楼40％的复印机需要进
行维护，如果第一座楼拥有公司60％的复印机，问这天在维护的复印机是多少？
20% * 60% + 40% * (1 - 60%) = 28%
4.要在一个接待室(reception room)里铺瓷砖，接待室的长18 meters，宽12 meters，
同时要修一条从大厅(hall)到楼梯(stair way)的通道（不铺瓷砖）占地50 square
meters，允许铺设时有35%的浪费(wastage)，1平方米瓷砖的价格是10美元，
问大约(approximately)要花多少钱？
(18 * 12 - 50) * 135% * 10 = 2,200
5.某公司要做一个车辆更新，有2种车型，一种是X(忘了，用X代替),一种是van，新X每
liter油走20公里，新van每liter油走15公里，旧X每liter油走15公里，旧van每liter油
走12公里。现在要开15000公里，其中有60％由van来承担，问更新后将节省多少油？
(15000 * 60% / 12 + 15000 * 40% / 15) - (15000 * 60% / 15 + 15000 * 40% /
20) = 250
6.有2个行政打字员(administrative typist)，A的速度是B的1 1/4 times，现在要打7

rate的尺度(dimension)是72,96,48，如果缩放到三个尺度的和是200，问最长的那个尺
度要缩多少？
96 * (1 - 200 / 216) = 64 / 9 = 7.1
10. 有一个矩形，长是宽的1 1/3 times，如果把每边增加1，面积将增加85，问长是多
少？
48
11.有一个printer，一小时能打12,000页，早上8:30开始打印，中途被打断2次，每次5
分钟，13:15打完，问总共打了多少页？
55,000
==========================================================
个人感觉IBM技术题考得很细，比如考数据结构，会给定一种应用情况需要怎样插入数据，在哪删除，如何查找问你选哪种数据结构，如顺序存储、单链表、双向链表、循环链表最合适；考算法复杂度，如快速查找的平均查找次数；考基本概念，如UML是什么，或者画一个UML的图，问你是引用，关联还是什么。C++主要考程序执行结果，编译错误等等。
在做C卷的时候，感觉自己读题速度太慢了，因为不习惯英文的技术术语，需要反应下是什么意思。我在做一个进程调度的题时，就花了很长时间读题，后来才反应过来是考各种算法，短作业，优先级调度，等等。很多术语换做英文就不认识了，所以准备考试的时候不防把常用的专业英文术语准备下，做一些这类英文题。
