Company Profile
Stanford University classmates Bill Hewlett and Dave Packard founded HP in 1939. The company's first product, built in a Palo Alto garage, was an audio oscillator—an electronic test instrument used by sound engineers. One of HP's first customers was Walt Disney Studios, which purchased eight oscillators to develop and test an innovative sound system for the movie Fantasia.

HP Pattern & Eperience
Four rounds
3.Technical(may be 2 rounds)
4.Hr
TEST (six sections)(214 attended)
Mostly venn diagrams, sums like $ for 0 , * for 1 and 5 qns asked from that)
b. OS
c. Data communication and networking (also some problems were asked)d. C and UNIX
e. DBMS
f. I don’t know d other section
GD(67 attended)
For my panel ,they asked discuss on our own topic
We choose Tea Vs Coffee
Here they will select half of the count I think so.
Technical (time was something around 10.30)(44 attended)
Since I told tat I am good in C, they asked to write two programs
1.swap 2nos using pointers2.string reverse using pointers
3.he gave one quantitative qn
4.some qns on DBMS (my area of interest) (foreign key,3cnf,)
5.asked about compiler (lex tool)
They expect cse graduate to work on unix
HR (time 12 passed)(17 attended & no elimination)
They will ask everything in your resume
Be prepared.
Technical
1.give the o/p of the following programs>>>
a)main()
{ printf("%d",scanf("%d%d",printf,scanf));
}
1)2 2)2 2 3)0 4)error
b)there was a program of swaping by pointer(check it out)
c)main()
{char *p="quick";
char q[]="sort";
char *t;
t=malloc(sizeof(p)+sizeof(q)+1);
strcpy(t,p);
strcat(t,p);
}
1)quick sort 2)sort sort 3)quickqick 4)sort quick
d)main()
{ int s[]={1,2,3,4,5,6};
printf("%d",&a[0]-&a[5]);
}
1)error 2)8 3)6 4)0
e)try to know pointer and its various operation (say what will happen if 2 pointer is added or int pointer is addressed to a char etc.)
4.try to know something about firewall and its functions

stuct
{
char a;
char b;
int a[2];
short d;

} name;
sizeof(naame) ans:16
note: consider c compiler unde unix for all c questions
c:
---------
1)main()
{
int i=1;
swith(i)
{
i++;
case 1: printf("case1");
break;
case 2: printf("case 2");
break;
default: printf("default");
}
ans: when we compile we get warning that unreachable code and if we execute we get "case 1"
will be printed.
2)questions related to funtcital pointers
3)some question on const char*p , char* const p;
HP interview questions
but it depends on who takes ur interview
1 tell @ urself
2 ur fav. prog. language
3 write string compare program in C (optimize it)
4 what is DML in oracle.
5 what is RDBMS? howz it different from DBMS?
4 What is abstraction? is it only in OOP or in C too? can we say printf func. in stdio.h is an abstraction?
5 how will u write a prog to perpare a report based on sorting files on date. i.e u have say 10 files and u have to sort them n make a report of them date of creation/ size - wize.
6 a question of java prog. where class was subclass of String and few output functions were there.
7 few questions on output in C related to pointers (easy)
8 Normalization? functional dependency vs. transitive dependency?
9 Unix - some easy ones.
----------------------------------------------------------------
2nd round
u know what is a test plan? is testing important? how will u estimate time taken for testing in product dev. LIFE cYCLE? given an estimation problem?kinds of testing? what testing a developer has to do ...order of different kind of testing....which is imp testing or development from risk point of view and from personal point of view. what id more imp. work or money?
----------------------------------------------------------------
3rd round
tell something about urself
....what do u know @ HP?
why looking for a change?
if u have done some cerification/course then why?
which are the good companies acc. to u and why?
why join HP?
