NVIDIA Software Engineer interview questions

1) Write a code for printing quotient and remainder of two numbers without using / and % operator

In most cases you need to have some experience with CUDA. If you want to increase your chances of getting a job offer you need to know very well about linked lists. We used the collabedit.com for the interview. It is like a chat but for coding. I got the following question on the screen of collabedit: // There is a chunk of memory in the kernel address space represented by kernelResource and an API exists to clear it. An IOCTL path exists to take a request from user-mode and using O/S services eventually dispatches to API_ZeroResource. From a security perspective what concerns do you have with this implementation? How would you fix them? // // KERNEL // BYTE kernelResource[10] = {0}; int API_ZeroResource( in_params *pParams ) { if (pParams->offset + pParams->length > sizeof(kernelResource)) return ERR_INVALID_LIMIT; memset(kernelResource + pParams->offset, 0, pParams->length); return 0; } // // USER // void ZeroResource() { in_params params = { ??? }; // an ioctl path exists to call API_ZeroResource ioctl( CMD_ZeroResource, ¶ms ); }
