Nvidia Interview Questions and Answers for 2024

About Nvidia

Founded in 1993, Nvidia is an American multinational tech company headquartered in Santa Clara, California. The company is behind introducing the world’s first GPU. It provides APIs and SoCs for mobile computing and is a global leader in artificial intelligence. Today, through software and hardware solutions, Nvidia leverages its potential to transform everything from gaming to transportation to healthcare.   

Nvidia Recruitment Process

The recruitment process begins with candidates applying for rules that match their interests and skills. They are required to submit their resume and apply directly through the company’s official website or via LinkedIn profile. Candidates can apply for multiple positions that match their skillset. After applying, the company will call for an interview if there’s a match. Nvidia interview process comprises four interview rounds:

• The Initial Recruiter Screen
• The Technical Phone Screen Interview
• The Nvidia On-site Technical Interview 
• Nvidia HR Interview Round

Nvidia Interview Questions for Freshers and Experienced 

1. What is the difference between union and structure in C?

2. What is an interrupt?

When a process or an event in hardware or software requires immediate attention, it emits the interrupt signal that alerts the processor of a high-priority process interrupting the current working process. In I/O devices, the Interrupt Service Routine (ISR) is dedicated to this purpose.  

3. What is the order of calling constructors and destructors in C++?

C++ constructor call order begins from top to bottom, i.e., from the base to the derived class. The C++ destructor call order is the reverse of the constructor. 

4. Explain passing by pointer and passing by reference.

Pass by pointer: Variables’ memory location is passed to the parameters in the function, and then the operations are performed.

Pass by reference: Enables a function to modify a variable without creating its copy. The user declares reference variables. The memory location of the parameter and the passed variable remain the same, and any change in the parameter gets reflected in the variable. 

5. What are composition and aggregation?

These two types of associations represent relationships between two objects. Aggregation implies that one object is the owner of the other, while composition means one object is contained in the other object. Destruction of the owning object affects the containing object in composition but not in aggregation. 

6. What is the difference between HTTP GET and HTTP Post? 

GET allows viewing something without changing it, and POST is useful for changing things. While GET helps retrieve remote data, POST is for inserting/updating remote data. For instance, a search page uses GET to obtain data, and a form that allows password change uses POST.

7. Explain pre-order, post-order, and in-order binary tree traversal.

• Pre-order: For creating a copy of the tree
• Post-order: For deleting the tree
• In-order: Gives nodes in non-decreasing order

8. What is the difference between heap and stack memory? 

9. What is RTTI in C++?

RTTI stands for runtime type information. This mechanism provides details about the type of an object at runtime. It is available only for classes with at least one virtual function. 

10. What operators cannot be overloaded in C++?

The following operators cannot be overloaded:

• . – Dot operator
• ?: – conditional operator
• sizeof – sizeof operator
• .* – dereferencing operator
• :: – scope resolution operator
• -> – member dereferencing operator

11. What are pure virtual functions?

A virtual function is a base class member function that can be redefined in a derived class. A virtual function can be declared using a virtual keyword. Contrastingly, a pure virtual function has no implementation and no body. It is declared by assigning 0. 

12. What is Nvidia TXAA?

Temporal anti-aliasing or TXAA is a spatial anti-aliasing technique applicable in computer-generated videos for combining information from past frames and the current frame. It helps create smoother and clearer images than other anti-aliasing solutions. TXAA combines high-quality MSAA multisample anti-aliasing, NVIDIA-designed temporal filters, and post processes. 

13. What is data hiding?

Hiding elements of a program's code from object members is called data hiding. It ensures controlled data access and the object's integrity, preventing unintentional or intended program changes. 

14. What is the difference between the assignment operator ( = ) and the equal to operator ( == )?

The assignment operator ( = ) assigns the value to the variable. It is sometimes used in complex equations.

The 'equal to' operator ( == ) functions as an equality operator for comparing two values. It returns true when the values are equal; else, it returns false.

15. What is containership in C++? 

The relationship between classes wherein one can create an object of one class into another is containership. The class that contains the object/ members of the other class is the container class. The object that becomes the part of another object is the contained object, and the object that contains the other object is the container object.
