Placement Papers decide your career. They are a very important test of your skills and its all up to them how your career shapes. So you have to dedicate some extra attention to Time Management for placement tests.

There are various parts of the placement paper pattern. The written test consists of multiple choice questions, sometimes theoretical technical questions, fill in the blanks types, technical language programs, opinions, comprehensions, opinion type, etc. When you start planning for your placement paper, you should first see the previous sample test patterns of that company. For example infosys sample placement papers are available are available free of cost online and you can download them for your practise. You must study the pattern and decide how much time you are going to dedicate on each type of question. And you must stick to what you plan.

There are various types of question in the aptitude part. The english language verbal questions do not take time as there is no calculation involved. You can save much time here to devote to other questions like math, quantitative and reasoning. In case of calculation type math questions, you should try to do it in the time you have set for each question and if you havnt done it, just leave it and move on to the next. If you have solved half of it, write the calculations on some rough paper for doing it later if you can save some time in the end.

You will come across many persons who will say that there were many questions which i could do but there was no time. What spoiled their chance in the placement test was their bad time management skills as they spent a lot of time on few questions which they could not actually do and as a result could not spend time on the easy questions they could do. So thats very important. Spend fixed time on each question. If you cant complete it, move on to the next and if you have time in the end, allocate some time to each question and do as many as you can. Attempt all questions if there is no negative marking in multiple choice type questions. Reserve the last few minutes for randomnly tick marking the choices for the remaining questions. You can practise using the time management techniques in your regular college exams and apply them in the recruitment or employment placement papers. You can greatly increase your chances of selection in the written test and getting eligible for the final job interviews.

Time Management is very important for your exams whether its a college placement test, school exam or a regular end of the year scheduled academic test. If you are properly prepared for the exam but are not good in time management, you may not have good scores. Bad management of the available time will make you lose out to your rival candidates. So its very important to properly plan how much time you are going to allot ot each question in the exam.
Planning the exposure to each question should be done very quickly. Normally a maximum of five minutes should be devoted at the beginning of the exam to study the questions in the question paper and deciding in your mind how much time you have to allot to each question. The questions of higher marks should get more time alloted while the small theoretical questions should have lesser time devoted to them. You should manage yourself in such a way that you dont spend more than a minute on any question than you decided previously. This would help you maximise your time utilization and prevent the depression arising out of concentrating more on one single tough question when you can do all the other ones easily.
The main purpose of time management is to maximise your output and prevent you from wasting your time and energy on one single tough problem in the exam. Keep in mind the total time of the exam, the number of questions asked, the type of questions and marks alloted to each question. Observe that these things for the initial five minutes and calculate how much time you should allot to each question. The time spent on each questions should not be more than the time alloted to the question by you plus one minute. You must stick to this rule whatever may happen.
When you are finished attempting all the questions you were confident of, you can again quickly see the number of questions pending and allot some time to each one. Then again atleast attempt those questions if there is no negative marking. In job placement test papers or campus recruitment exams, if you have negative marking then you should not attempt the questions you are not confident of. But if there is no negative marking in placement papers or college academic exams, you must attempt all questions whether they are multiple choice type or theoretical type. Its always better to write or tick mark something than leaving the question unattempted.
Thus polishing your time management skills is as important as your regular studies. You can practise in regular monthly tests or Pre-exams and apply the experiences in the final exams. This way you can have better scores and ‘output’ from your knowledge and outscore your ‘hard to beat’ competitors!

Motorola India came for campus placement at Trivandrum College on 7th October 2007.

i am providing the sample test paper and selection procedure for Motorola India Pvt. Ltd. (GSG - Global Software Group)test held at College of Engineering campus.

1. Pre – Placement Talk
They give a ppt or paper presentation during which one can know about the company. You have to listen to it carefully as they sometimes ask questions about the things they tell you in ppt.

2. Motorola Test Question paper
The test was very short. There were 30 questions to be done in 30 minutes. There were separate sets of questions for Electronics ece and Computer Science cse streams.
For computer science students, the questions were from the important degree subjects like OS, Data Structures, C/C++, Networking, Aptitude (Logical and Quantitative). There was no negative marking in the motorola exam.

3. Motorola Technical Interview
After the exam, there was a detailed technical and personal interview. They took a lot of time for every candidate. Asked all types of technical questions and test all your tech skills. What you write in your resume, it matters a lot and they ask questions according to that. You can also be asked about your projects and related questions.

4. Motorola HR Interview
The HR interview was somewhat tough. Some persons could find it hard to answer the questions. But dont worry and stay confident. If you have done well in the tech interview round, then you can do this one easily. good luck for that.. those who passed the interviews were given offer letters. You can prepare and practice using other previous placement exams test question papers here and the technical section problems of other companies tests.

C programming language - technical question paper for Quark Software india pvt. ltd.
Its popular products are QuarkXpress, QuarkCopyDesk, XTensions Software, XPert Tools Pro, etc.

See the following technical exam questions (multiple choice type) for quark publishing software developer job - employment test:

Note : There are 20 questions and no negative marking.
Time allotted is 30 minutes

1. What is the output of the following code
main()
{
printf(”Hello %d”,printf(”QUARK test? “));
}
a. Compile time error.
b. Hello QUARK test?
c. Run time error.
d. None of the above.
e. Quark Test ?Hello.

Ans. d.
This is because the evaluation of the parameters in a function call is done from right to left, becz the parameters were passed via a stack hence the first parameter (the leftmost one) is at the bottom of the stack and the rightmost parameter (if it is an expresseion, it will be evaluated before putting it on the stack) is on the top of the stack, hence while popping the parameters from the stack, the function printf (or any other function) gets them in the reverse order, i.e., from right to left, hence the statement printf(“Quark test? “) gets evaluated first while pushing it as a parameter on to the stack, and then the statement printf(“Hello %d”) is executed. The ‘12’ is the result of the return of printf(“Quark test? “) which returns the number of characters printed.

printf(”%d\t”,++(i++));
}

a. Compilation error
b. Runtime error
c. 256
d. 0
e. None of the above

Ans. Compile Time Error ‘Lvalue Required

4) What shall be the output of the following code?
main()
{
char i = ‘a’;
printf(”%c \t %c \t”, i ,(++i));
}
a. a b
b. Compile time error
c. b b
d. a a
e. 65 66

Ans. b b

5) What shall be the output of the following code?
main() {
int i,j;
printf(“QUARK %s\n”,main());
}
a. Compilation error.
b. Run-time error
c. Continuous scrolling Quark on the screen.
d. None of the above.

Ans. There is nothing on the screen and prog waits till the memory lasts and then out of memory run time error, so ans is b.

6) What shall be the output of the following code ?
#define f(x) x*x*x

main(){
printf(”\n%d”,f(2+2));
}
a. 8
b. 64
c. 10
d. 12

Ans. f(2+2) will expand to 2+2*2+2*2+2
= 2+4+4+2
= 12

7) What shall be the output of the following code ?
main()
{
void fun1(void *);
char a[] = “quark”;
void *temp;
temp = a;
fun1(temp);}
void fun1(void *temp1 )
{
int t1 = 0;
while(*((char*)temp1+ t1++ )!=’\0′) {
printf(”%c”,*((char*)temp1 + t1));
}
}

a. Compilation error
b. ark
c. quark
d. uark

Ans, uark

8. What will be the out put of the following code?
void main()
{ int x=3;
printf(”%d\t %d”,x>>1, x<<3);
}
a. 1 and 4
b. 1 and 24
c. 1 and 27
d. None of the above

Ans. 1 and 24
This is because 3 in binary is 00000000 00000011 in two bytes (integer). Again, the right to left evaluation rule of parameters is applicable and so x<<3 gets executed first, it means left shift 3 times, but this operator does not change the value of x itself, it simply returns a value, so x retains its value after this operation has been carried out, so we get 00000000 00011000 which is 24, so 24 is pushed onto the stack, and then x>>1, right shift 1, 00000000 00000011, which is 1 in decimal, so 1 is pushed onto the stack, then printf(”%d\t %d”) gets executed displaying 1 24.

9. What will be the result of the following code?

int *x;
x =(int *) 15;
a. Compilation error
b. Compiles but gives a runtime error
c. Absolute location 15 in the memory space shall be assigned to pointer x;
d. Location 15 in the program space is assigned to pointer x;
e. Location 15 contains the address to an integer.

Ans d

Quark India Placement Paper sample C programming language multiple choice questions from the Technical Tech Section of the question paper:

1. What will be the out come of the following code?

#include

int * func(){
static int x=0;
x++; return &x;
}
int main()
{
int * y = func();
printf(”%d”,(*y)++);
func();
printf(”%d\n”,*y);
return 0;
}

a. Compilation error.
b. Prints 1 and 3
c. Prints 1 and 3 but it is not good practice.
d. Prints 1 and 1
e. The code will not execute properly because y points to a variable whose life span is limited to execution of the function func();

Ans. Prints 1 and 3 but it is not a good practice

2. Referring to the above code , which of the following would be the correct
implementation for myFunc ?
char *format = “%d”;
int main()
{
int x;
myFunc(scanf,&x);
printf(“%d\n”,x);
return(0);
}

a. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,&x);}
b. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,*x);}
c. void myFunc(int*y(const char*,…),int *x) {(*y)(format,&x);}
d. void myFunc(*(int y(const char*,…)),int *x) {(*y)(format,x);}
e. void myFunc(int(*y)(const char*,…),int *x) {(*y)(format,x);}

3. What shall be the output of the following C code?
void main()
{
unsigned int x= -1;
int y =0;
if(y<=x) printf(“A is true\n”);
if (y = =(x = -10)) printf(“B is true\n”);
if ((int) x>=y) printf(“C is true\n”);
}
a. A is true.
b. B is true.
c. C is true.
d. None of the above.
Ans. A is true because x contains –1, i.e., in binary it is ffff, i.e., all 1s, so being unsigned, all 1s are interpreted as the value 65535 and not as –1 (however, all 1s are interpreted as –1 if it is just an int), hence y<=x returns true.

4. In the following code what is the correct way to increment the variable ptr to
point to the next member of the array

union intfloat
{
int intArray[ 5];
float floatArray[ 5];

};
union intfloat arr[20];
void *ptr =arr;

a. ++(int*)ptr;
b. ptr = ptr+5;
c. ptr = ptr +sizeof(*ptr);
d. ptr = ptr+sizeof(intfloat.floatArray);
e. ptr = (void*)((union intfloat*)ptr +1);

Ans. e. ptr = (void*)((union intfloat*)ptr +1);

5.What shall be the output of the following program?

#define PRINTXYZ(x,y,z) printf (#x "=%d\t" #z "=%d\n", x, y)

void main() {
int x, y, z;
x=0; y=1; z=2;

x || ++y ||++z;
PRINTXYZ(x,y,z);

++x || ++y && ++z;
PRINTXYZ(x,y,z);

++x && ++y || ++z;
PRINTXYZ(x,y,z);
}

a. Compilation error.
b. Runtime error.
c.
x=0 z=2
x=1 z=3
x=2 z=4
d.
x=0 z=2
x=1 z=2
x=2 z=3
e. None of the above.

Ans. d.

6. What shall be the output of the following code ?

main()
{
printf(“%d %d”, sizeof(NULL), sizeof(“”));
}

a. 1 and 0.
b. 0 and 1
c. 2 and 1
d. 4 and 1
e. None of the above

Ans. Depends on the machine and compiler. Actually it is the sizeof(int) and sizeof(char) as a string is stored as a char array terminated with 0, so sizeof(“”) gives 1, whereas sizeof(“adsf”) gives 5 (including the terminating 0). So in TurboC we get c as the answer, on VC we get d as the answer, so I guess e is the ans, i.e., None of the above.

7. What shall be the output of the following code?

int *check ( int,int);
void main()
{int c,d;
c = check(11,29);
d= check(20,30);
printf("\nc=%u",c);
}
int * check(int i,int j )
{
int *p, *q;
p=&i;
q=&j;
if(i>=95)
return(q);
else
return(p);
}
a. 11
b. 29
c. Compilation error
d. Runtime error
e. None of the above.
Ans. e. None of the above. the statement c = check(11,29) is assigning an int ptr to an int, so c has an address of an int (which has gone out of scope, since the function returns the address of a variable which had its scope only inside the function, since the parameters were passed by value) so the value printed can be anything. Instead, if the statement was c = *(check(11,29)) then c would have the value stored at the address returned by the function, which would most probably be 11, but it cannot be guaranteed since the variable i has fallen out of scope.

8. What shall be the output of the following code?

void main()
{int a[3][2]={ 1,2,
5,7,
6,8};

printf(”\n%d”,((a+1)-(&a+1)));
}
a. 0
b. -16
c. -2
d. -8
e. None of the above.

Ans. –2. I haven’t been able to figure this one out. a is the address of the 2-d array, here a, &a, *a all give the same value, i.e., address of the array. (a+1) gives the address of the second row, it is the same as a[1]. *(a+1) gives the address of the first cell of the second row. **(a+1) gives the value of the element stored in the first cell in the second row. (*(a+1)+1) gives the address of the second cell of the second row. *(*(a+1)+1) gives the value of the element stored in the second cell in the second row.

9.What shall be the output of the following code?
main()
{
char str1[]=”Hello”;
char str2[]=”Hello”;
if(str1= =str2&& (*(str1+6)= =*(str2+6)))
printf(”\n Equal”);
else
printf(”\n unequal”);
}
a. Equal
b. Unequal
c. Compilation error.
d. Runtime error.
e. None of the above.

Ans. b. Unequal, because the addresses of the two strings are str1 and str2 and they are different.

10. Given that sizeof(int) is 2 , what is the output of the following code
main()
{
int a, b=255,c=127;
a=~b;
c=c^(~a & b|0);\
c=c^(~(~b));
printf(”%d\n”,c);
}
a. Error because of overflow;
b. 255
c. –256
d. 127
e. None of the above
Ans. d. 127
