IBM藍色之路2023暑期實習生計劃 筆試資料、地點、時間

以下內容是根據IBM2009暑期實習筆試的內容整理的，不代表今年的筆試方向，所以僅供各位參考！

IBM筆試主要考察學生的邏輯思維水平和推理能力，筆試為全英文，對英語的閱讀能力要求比較高。

1.筆試題型：

1-15題 數據處理題（DM），13分鐘 15道題；
16-35題 數字序列題（NS）， 4分鐘 20道題；
36-47題 數學推理題（MR），15分鐘 12道題；

2.題型備考資料

1）數據處理題：即矩陣題

1.一共有三個5*5的矩陣，每個矩陣5小題，大概有這樣一些：把所有的W替換成2，所有的Y替換成6，所有的X替換成4，哪一行和哪一列的和等于18？
把第四列反轉，把第2行和第二列替換，第三列第四個下面的數字是什么？
把出現了數字2次數最多的那一行的出現的唯一一個字母從矩陣中刪掉，它出現在矩陣其他地方的次數減去3出現的次數和4出現的次數減一是多少？
把每一個出現在數字2和3左邊的'字母全部與他們右邊的數字交換，出現在數字最多的那一列的兩個字母是？
2.開始給出一個4×5的矩陣，然后矩陣中的元素是類似于a,b,c,d這樣的字母，題目有某一行中出現次數最多的元素是什么，這樣的比較簡單，還有從某個元素開始按逆時針或是順

時針方向旋轉得到的元素是什么之類的，這樣的就比較麻煩。

題目介紹：
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 outs
ide 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：根據題意，從第5列第4個字母開始，在矩陣元素外沿順時針方向走，在第2個E字母和第2個B字母之間的第二個字母應該為C，如圖所示：

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：根據題意：（1）字母比數字多的行有第1行、第3行、第5行；（2）數字只被1個字母隔開的行只有第1行；（3）在第1行中，從右往左數，在第2個數字（即2）之前的字母應

該為C。
這道題的關鍵是找出題干中要求的那一行，其中最后一個條件：這一行的數字之和要小于第二列的數字之和（即1+1+5=7）可作為排除第5行的依據。

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：如果將第4行的字母倒轉，則第4行變?yōu)椋篊 A D E B，則在第5行字母E的上面的字母就是變化后的低行，從右往左數的第2個字母E。
tips：
搞清楚題目考察的位置，row,column,diagonal,reverse這些詞要搞懂，然后用什么替代什么也搞搞清楚，可以用筆簡單標一下，鉛筆和黑色水筆區(qū)分開兩次標記，然后再用其他字

跡的筆標另外一次，關鍵是讓自己看明白。最高境界大概是不標直接看！
主要是時間不太夠，這個部分拼得就是速度
2）數字序列題
基本上都是兩個一組，三個一組，全是一個規(guī)律：連續(xù)幾個數字，跳一個，再連續(xù)幾個數字。
題目介紹：
It consists of number series. In some institutes alphabetical series is given instead of number series.
1. 30,28,25,20,34,28,?
a:21
2. 4,8,16,32,64,128,?
a:256
3. 8,16,24,32,40,48,?
a:56
4. 13,11,14,12,15,13,?
a:16
5. 6,18,36,108,216,648,?
a:1296
6 4,4,8,8,16,16,?
a:32
7. 2,6,18,54,162,486,?
a:1458
8. 4,20,35,49,62,74,?
a:85
9. 10,18,15,23,20,28,?
a:25
10. 4,10,8,14,12,18,?
a:16
11.10,15,12,17,14,10,?
a:16

tips：這部分時間是最緊張的，看了題目直接在答題卡上劃個線標出來，然后hr收試題的時候再慢慢去涂到你覺得最漂亮為止，千萬別在試題卷上標記答案而沒有在答題卡上標，

這樣既浪費時間而且可能等下試卷被收了還沒把答案涂到答題卡上。

3）數學推理題

繁瑣的數學，像初中的分數應用題，計算量比較大，全是小數點和分數。
中文：
1.有3臺復印機（copier），平均每臺每周工作42小時，每臺每周最少工作35小時，問一臺復印機每周最多會工作多少小時？
42*3 - 35*2 ＝56

2.在一個長11 meters，寬6 meters的房間里，鋪上10 centimeters厚的水泥，問需要多少水泥？
11*6*0.1＝6.6 cubic meters

20% * 60% + 40% * (1 - 60%) = 28%

4. 要在一個接待室(reception room)里鋪瓷磚，接待室的長18 meters，寬12 meters，同時要修一條從大廳(hall)到樓梯(stair way)的通道（不鋪瓷磚）占地50 square meters

，允許鋪設時有35%的浪費(wastage)，1平方米瓷磚的價格是10美元，問大約(approximately)要花多少錢？
(18 * 12 - 50) * 135% * 10 = 2,200

5. 某公司要做一個車輛更新，有2種車型，一種是X(忘了，用X代替),一種是van，新X每liter油走20公里，新van每liter油走15公里，舊 X每liter油走15公里，舊van每liter油走

12公里�，F在要開15000公里，其中有60％由van來承擔，問更新后將節(jié)省多少油？
(15000 * 60% / 12 + 15000 * 40% / 15) - (15000 * 60% / 15 + 15000 * 40% / 20)= 250

6.有2個行政打字員(administrative typist)，A的速度是B的1 1/4 times，現在要打72頁文件，問快的那個人打了多少頁？
72* 5/9 = 40

tips：
直接在試卷上打草稿，不要在一道題目上糾纏太久，算了沒答案就猜一個，有很多是不用算可以直接看答案猜的。大家考了這么多年試，選擇題的什么排除法，xx法，都了然于胸

了。
