Background info: D.E Shaw has a reputation of hiring only top mathematicians, researchers, etc.
"They have these really elitist-sounding recruiting philosophies, like, 'If you're brilliant we'll hire you,'" says one insider about D.E. Shaw's hiring process. Indeed, the firm founded by a Computer Science professor boasts that it includes a disproportionate amount of computer scientists and systems architects, and that it extends an offer to only one out of about 150 of the candidates it considers. It's even harder to get an offer at the firm these days than in boom times; insiders report that the firm is in a deep hiring freeze.

Part I: Programming
1. Swapping two variables x,y without using a temporary variable.
2. Write a program for reversing the given string.
3. The integers from 1 to n are stored in an array in a random fashion. but one integer is missing. write a program to find the missing integer.
4. Write a c program to find whether a stack is progressing in forward or reverse direction.
5. Write a c program that reverses the linked list.
C/C++:
1.
what does nodeptr stand for?
2.
int *x[](); means
expl: Elments of an array can't be functions.
3. What is the output?
ans: 4
4.
What is the output
5.
ans: no error. But It will over writes on same
file.
6.
8. what is the output of
a) 13 b) 12 c) 44 d) 14
9.
10.
11.
12.
13.
14.
15.
16. what is the o/p of the program
main()
{
int rows=3,colums=4;
int a[rows][colums]={1,2,3,4,5,6,7,8,9,10,11,12};
i=j=k=99;
for(i=0;i
17. what is output
a) infinite loop
b) error
c) 99..99..99..99

Are these questions an accurate representation of the real interview?
