Cracking the Nvidia interview can be challenging even for skilled developers. Candidates should practice answering the most common Nvidia interview questions because their answers in the final interview will show how enthusiastic and interested they are in the job and the company, as well as how much technical knowledge they have. During the Nvidia interview process, candidates will be asked to show how well they can solve difficult system design and coding issues. To ace the interview, you need to practice hard and make a plan to cover all the important things from the interviewer’s point of view. Â.

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, Nvidia uses its power to change everything from games to transportation to healthcare through software and hardware solutions.   Â.

The recruitment process begins with candidates applying for rules that match their interests and skills. It is required that they send their resume and apply directly through the company’s website or 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:

Getting hired at a top technology company like Nvidia is no easy feat. The Nvidia interview process is rigorous, with multiple intense rounds of technical and behavioral questions aimed at evaluating your skills, passion, and problem-solving abilities.

As someone who has gone through the process and landed a job at Nvidia I want to share the most common and tricky Nvidia interview questions I came across to help you prepare. This comprehensive guide covers both the technical coding and systems questions as well as the critical HR and behavioral prompts.

Let’s dive in!

Brushing Up on Key Nvidia Interview Technical Concepts

Before we get to the specific questions it’s crucial that you brush up on key technical concepts Nvidia focuses on like

  • Computer architecture and organization
  • Operating systems fundamentals
  • Algorithms and data structures
  • Object-oriented analysis and design
  • Computer graphics and image processing
  • Parallel computing and GPGPU concepts
  • AI/ML frameworks like TensorFlow and PyTorch

Having a strong grasp of these areas shows the interviewers your broad base of knowledge to work at a core technology company like Nvidia.

Now let’s look at some of the most common coding interview questions asked:

Nvidia Coding Interview Questions

Q1: Reverse a Linked List

This is a common coding problem that tests your familiarity with fundamental data structures. Outline the iterative approach:

  • Initialize previous, current and next nodes
  • Iterate through the list from head to tail
  • Change next of current node to previous
  • Set previous to current, current to next

Q2: Find Missing Number in Array

To find the missing number in a sorted array of distinct elements:

  • Initialize variable missing = length of array
  • Iterate through array and update missing -= array[i]
  • Return missing

This uses the formula for sum of first n natural numbers.

Q3: Implement a Stack using Queues

Use two queues q1 and q2:

  • For push operation, enqueue to q1
  • For pop, dequeue everything from q1 and enqueue to q2, dequeuing from q2 returns the popped element.

Swapping the queues reverses the process.

Q4: Find Kth Largest Element in Array

  • Build a max heap of first k elements
  • For remaining array elements, if greater than root, replace root with that element
  • Once array is processed, root holds kth largest element

Q5: Print All Permutations of a String

Use recursion:

  • Base case: if string is empty, print it
  • For each iteration, fix character at index and find permutations of remaining characters
  • Once recursive call returns, print the fixed character with each permutation of remaining ones

This builds up all combinations.

Now let’s look at some examples of system design questions:

Nvidia System Design Interview Questions

Q1: Design a Live Video Streaming Platform

  • Have ingestion servers to receive and chunk video streams
  • Store chunks in distributed object storage like S3
  • Use transcoding services to encode formats for playback
  • Leverage CDN to cache streams close to viewers
  • Playback via media servers providing different bitrates
  • Collect analytics for optimization

Focus on scalability, high availability, and low latency.

Q2: Design a Ride Sharing App

  • Maps and geolocation services to match drivers/riders based on location
  • Payment gateway to handle transactions
  • Real-time messaging system to notify matches
  • Load balancing across matching servers
  • Caching frequent queries on riders’ locations
  • Analytics pipeline from usage data

Discuss tradeoffs and optimizations.

Q3: Design an API Rate Limiter

  • Use counters to track requests from API keys
  • Check counter before each request and reject if exceed limit
  • Reset counters periodically based on expiry window
  • Have distributed counters for horizontal scaling

Q4: Design a News Feed Feature

  • Have feed generation servers pull latest posts and rank by relevance
  • Store feeds in memory cache for low latency delivery
  • Push updates to subscribed users’ feeds via messaging queues
  • Pull cached feeds on demand when users request
  • Purge stale caches asynchronously after expiry

Now let’s move on to the critical HR and behavioral part of the interview.

Nvidia HR Interview Questions

Q1: Tell me About Yourself

Focus on your technical background, relevant projects, and passion for technology. Share why Nvidia’s mission resonates with you.

Q2: Why Do You Want to Work at Nvidia?

Show enthusiasm for their industry leadership in GPUs, AI, and graphics. Highlight projects or skills you want to develop there. Convey eagerness to contribute.

Q3: How Do You Handle a Difficult Co-worker?

Emphasize communicating directly and respectfully to understand their perspective. Explain how you’d find common ground and collaborate where possible. If issues persist, involve management while maintaining composure.

Q4: How Do You Prioritize Tasks With Competing Deadlines?

Explain balancing business impact, resources required, and dependencies. Share gathering input from stakeholders on priorities where possible. Outline tracking all tasks and reevaluating as new needs emerge.

Q5: When Have You Handled a Major Crisis or Failure?

Share a specific example that demonstrates resilience, accountability, and ability to course correct after setbacks. Explain lessons you learned in the process.

Q6: Where Do You See Yourself in 5 Years?

Outline your ambition for taking on greater technical challenges and responsibilities in the organization like leading projects or teams. Share your ongoing focus on development skills and passion for technology.

Preparing responses for questions like these ensures you can highlight your strengths as a candidate while answering thoughtfully and professionally.

Tips for Nailing the Nvidia Interview

Here are my top tips for acing your Nvidia interview:

  • Practice aloud – verbalizing your approach to technical questions out loud is critical preparation. It will help structure your thoughts clearly and coherently.

  • Clarify ambiguities – don’t hesitate to ask for clarification on any unclear aspects of technical prompts before diving in. This shows thoughtfulness.

  • Explain your logic – walk through your approach and code step-by-step. Sharing your thought process is just as important as your solution.

  • Brush up on fundamentals – review core CS concepts like data structures, algorithms, OS, networking, and OOP principles which are frequently tested.

  • Highlight passion – convey genuine enthusiasm for the role, Nvidia’s technology, and the industry at large. This leaves a strong impression.

  • Prepare stories – have clear examples ready highlighting your qualifications for behavioral questions. Tie them back to the role.

By mastering both the technical and HR components, you’ll prove you have what it takes to excel on the team at one of tech’s top companies. Wishing you the very best in your pursuit of a career at Nvidia!

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

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. Â.
