Nvidia Hardware Programming Mostly Interview Questions and Answers

Q1. Which is the best sorting algorithm
Ans. 
There is no one-size-fits-all answer as the best sorting algorithm depends on the specific use case and constraints.
• The best sorting algorithm depends on factors such as the size of the data set, the range of values, whether the data is mostly already sorted or not, and the available memory.

• For small data sets or nearly sorted data, insertion sort or bubble sort may be efficient.

• For large data sets, quicksort, mergesor...read more

Q2. Types of Memory Allocations in C
Ans. 
Types of memory allocations in C include static, dynamic, and automatic.
• Static memory allocation: memory is allocated at compile time and remains constant throughout the program's execution. Example: int x = 5;

• Dynamic memory allocation: memory is allocated at runtime using functions like malloc() or calloc(). Example: int *ptr = (int*)malloc(sizeof(int));

• Automatic memory allocation: memory is allocated on the stack and...read more

Round duration - 90 Minutes
Round difficulty - Medium

The timing was from 4:30 pm to 6 pm, so it was quite convenient. The platform was good, the only problem I had was while attempting diagram based questions, as the interface was difficult to understand. The test had three types of questions- MCQ, subjective and diagram based. The major topics from which the question were asked were- sequential circuits(sequence detector), static timing analysis, digital design and computer architecture.

The timing for my interview was 9:30 pm and it went on for an hour. They asked me thorough questions from majorly two topics- CMOS and Digital System Design. Even if I was not able to answer certain questions,, they were happy to drop hints and then observed how I went further with the solution.

Q1. 
Wildcard Pattern Matching Problem Statement
Implement a wildcard pattern matching algorithm to determine if a given wildcard pattern matches a text string completely.
The wildcard pattern may include the...read more
Ans. 
The task is to implement a wildcard pattern matching algorithm that checks if a given wildcard pattern matches a given text.
• The wildcard pattern can include the characters '?' and '*'

• '?' matches any single character

• '*' matches any sequence of characters (sequence can be of length 0 or more)

• The matching should cover the entire text, not partial text

• Implement a function that takes the wildcard pattern and the text as inp...read more
