HCL - HP
Written test:
One GRE type anals. section, and two comp Sc. sections. One Comp Sc. section was problem solving type. Quite easy. Only question worth mentioning in it was:
You are given a stack on which you can do the following:
Push X ----push the contents of memory location X on the stack
Pop X ----pop the contents of top of stack into mem. loc X
AND ----pop top two elements of stack, AND them and push theresult onto stack.
NOR ----pop top two elements, NOR them and push the result onto stack.

Given two data elements at memory locations A and B, obtain A XOR B usingthe above.

First Interview:- mostly technical.
a) Asked about my B.E. and why I joined MS.
b) My preference of posting. They asked this initially before launching into any other questions. Remainder of the interview was mostly on OS and C. Nothingon networks. They frame their questions on the basis of what you specify as your preference of posting and depending on what projects are available there.
c) What architectures, apart from 8085, do you know?
d) Give the contents of process stack for the execution of a particular C-program they give.
The C-program as such is not important. You just have to remember the order in which the return address of any function/procedure call, the parameters, and the local variablesare stored on the stack.( I guess, any CO book should have this. Maurice Bach talks about user and kernel stacks)
e) What all are shared by parent and child processes immediatelyafter parent executes a fork system call? Cross questioned about the 'copy on write' facility and 'dup' system call.--- again see MB, and also Stevens' 2nd chapter.
f) What events happen when the following command is given?cat /etc/passwd more---- Describe how the shell forks the two processes and how the pipe gets created between them. Cross question: How does 'cat' know that its output has to be written into the pipe and not into standard o/p?
g) Have you written any TSR's? --- No. What are TSR? ----Terminate but stay resident programs. Then does it mean DOS is a multitasking system?---- No, TSRs are interrupt driven
h) How are Windows programs different from normal C-programs?---- Windows programs are event driven. What can be the various types of events? --- See Primer/API bible.
i) Difference between swapping and paging.---- Swapping is moving entire processes between main memory and hard disk. Paging is moving individual pages of a process.
j) Write a program to list all palindromes in a string.
Hint: use a stack and some extra storage for remembering previous palindromes.
k) What's the outout?
char *cp;
int *ip;
cp=(char *)0x100;
ip=(int *)cp;
ip++;
cp++;
printf("cp = %x ip = %x", cp, ip);
Ans:cp = 0x101 ip = 0x102
l) What are static variables and functions? There are two files,say, file1 and file2. file1 has a global declaration static int x; file2 has a global declarationint y; What is the difference between the two types of declarations when you link file1 and file2?--- x is local to functions in file1 and cannot be seen by functions in file2. y can be seen by functions in both file1 and file2.
m) How does a debugger set breakpoints in a code you are debugging?---- some funda regarding insertion if an interrupt instruction in the code....don't know for sure. This was followed by a shady psychological test. You are given a set of six pictures. Look at each picture and write a story on each.

Second interview:
(fully personal --- more interesting;-)
a) What did you feel about the ppt? --- wasn't very impressive
b) Have you heard of creativity? -- Ya. Have you heard of Bernard Shaw? -- Ya. (Then he rattled off some quote of BS regarding creativity) What do you say? --- I put some shadiest fundaes regarding visionaries and Leonardo da Vinci conceptualising Helicopters in his time!************************************************************************

NOTE: If you have been offered a job previously by any other company after your BTech/BE or if you have even slightest of work experience then make it a point to mention about it. It is a major plus point. The interviewers will be definitely interested in knowing that some other company also found you good enough to be selected.
