I applied through an employee referral.

HR called and arranged for a telephonic interview.

The senior developer called and conducted the interview for one hour.

Requirements included:

• C program basics in depth
• OS in depth
• Graphics and CUDA basics

How to use a variable declared in one file and accessible in another file.

Count the number of set bits in a user-defined 64-bit number. Optimize it to the highest level.

Detect memory leaks using wrapper functions.

Which will exit/hang faster and why:

while(1) int ptr = (int*)malloc(100);

while(1){ int ptr = (int*)malloc(100); memset(ptr, 1, 100); }

There are K sorted arrays of size N each. Merge the arrays into a single sorted array of size KN.
