Nvidia Interview Questions, Process, and Tips

College Name: n/a

Round: Test
Experience: 4 sections, no negative marking but they had sectional cut-off.Section 1 (C, C++ ):
15 questions.
Mainly questions of type what will be output of following, type of error.(compile time or run time ,etc.) [Do pointers, pointer to functions and OOP concepts in detail]
This section was quite easy.
Section 2 (Operating System):
10 questions.
Questions on deadlock, process scheduling, priority inversion , look-aside buffer memory, etc.
This section wasn’t that easy…..Section 3 (Data Structures):
8 questions.
DSA questions on sorting, searching , graph traversal (BFS n DFS),Minimum spanning tree (Prim and Kruskal algo), Shortest path(Dijkstra’s algo).
Time complexity related questions and applications of all above mentioned topics. No straight forward questions.
Toughest section of apti.Section 4 (Quant):
8 questions.
Questions on probability, series , simple logic puzzles.
Easiest section of apti.
No. of people shortlisted after the aptitude test = 20
Coding Test (2 Questions 30 min)3 questions were there out of which we had to solve only 2
1. Implement stack (push and pop) operations using linked list.
2. Find the first non-repeating character in a given string in O(n) time complexity.
3. Given co-ordinates of two rectangles find co-ordinates of intersecting rectangle.
No shortlist after this

Round: Technical Interview
Experience: 4. What is polymorphism? What is virtual function…? How will you implement if I tell you to develop compiler?
I said, I will maintain a static table to store pointers of virtual functions for each class…so it can be accessed by all objects….and my call to virtual function will be converted as…..
p->fun_ptr->fun()….where p is my pointer to object.(He said this is another use of function pointer)

17. In class of 100 students there are 24 girls and 32 boys….no 3rd gender person…..
I gave him confused look….and asked how it is possible…? He said that is the question…you tell me….and told me to write equation….
I wrote on paper……32 + 24 = 100

College Name: NA

Round: Test
Experience: 1 question on cache miss.



1 question on CMOS circuit design for MUX
Tips: Learn basics very well. 



Digital IC design  - RC delay calculation, designing circuits using CMOS, transmission gates, NMOS, memory design etc.



Computer Architecture - problems oriented - so learn cache miss, no of bits calculation problems, MIPS, etc.



Digital Systems -



Some logic questions - learning to use divide and conquer, stack, queues, hashes on non-programming problems,

General Tips: If you have done any work which is related to NVIDIA, it might help.

In my case, I have worked in CUDA for my project.
