shortest_distance = len(word_list)
def recursive(current_word, all_taken_words):
nonlocal begin_word, end_word, word_list, shortest_distance
if current_word == end_word:
if len(all_taken_words) < shortest_distance:
shortest_distance = len(all_taken_words)
return
for word in word_list:
if word not in all_taken_words:
diff_cout = 0
for letter1, letter2 in zip(word, current_word):
if letter1 != letter2:
diff_cout += 1
if diff_cout == 1:
recursive(word, all_taken_words + [word])
recursive(begin_word, [begin_word])
return shortest_distance

“To evaluate the effectiveness of a new feature in NVIDIA’s developer tools, I would design an A/B test following standard principles of experimental design. First, I would formulate a clear hypothesis regarding the expected impact of the new feature on user engagement or productivity. Next, I would randomly assign users into two groups: the control group, which uses the existing version of the tool, and the experimental group, which uses the version with the new feature enabled. To ensure statistical validity, I would determine the sample size required to detect meaningful differences in the chosen metrics with sufficient power. Additionally, I would select appropriate metrics, such as user engagement or productivity, to measure the impact of the new feature. By carefully designing and conducting the A/B test, we can objectively evaluate the effectiveness of the new feature and make data-driven decisions regarding its implementation.”
This question evaluates your ability to analyze performance benchmarks for NVIDIA products using statistical methods, identify significant differences between products, and account for potential sources of variability.

Example
“I would employ statistical methods to compare performance metrics across different products and configurations. First, I would conduct hypothesis tests, such as t-tests or ANOVA, to determine whether there are significant differences in performance between products. If significant differences are detected, I would then perform post-hoc tests, such as Tukey’s HSD test or Bonferroni correction, to identify which products or configurations differ significantly from each other. Additionally, I would carefully consider potential sources of variability, such as hardware configurations, driver versions, or benchmarking methodologies, and incorporate appropriate controls or statistical adjustments to account for these factors. By rigorously applying statistical methods, we can ensure accurate and reliable performance comparisons for NVIDIA products.”
This question evaluates your understanding of the p-value concept in hypothesis testing and how it is used to determine the statistical significance of the results.
How to Answer
Explain the definition of a p-value, its interpretation in hypothesis testing, and how it is used to assess the strength of evidence against the null hypothesis.
Example
“In hypothesis testing, the p-value is the probability of observing a test statistic as extreme as, or more extreme than, the one calculated from the sample data, under the assumption that the null hypothesis is true. A low p-value indicates that the observed data are unlikely to have occurred if the null hypothesis is true, suggesting evidence against the null hypothesis and in favor of the alternative hypothesis. Typically, if the p-value is below a predetermined significance level (e.g., 0.05), we reject the null hypothesis in favor of the alternative hypothesis, concluding that the observed effect is statistically significant.”
Your NVIDIA data analyst interviewer will evaluate your understanding of overfitting in machine learning models and how techniques like regularization can help prevent it.
How to Answer
Discuss the concept of overfitting, its causes, and consequences in machine learning models. Then, discuss how regularization techniques such as L1 and L2 regularization can help mitigate overfitting by imposing constraints on the model’s complexity.
Example
“In machine learning, overfitting occurs when a model learns to capture noise or random fluctuations in the training data, rather than underlying patterns, leading to poor generalization performance on unseen data. Overfitting often occurs when the model is overly complex relative to the amount of training data available, allowing it to memorize the training examples rather than learn meaningful relationships. Regularization techniques such as L1 and L2 regularization address overfitting by adding penalty terms to the loss function, which discourages overly complex models. By incorporating regularization into the training process, we can prevent overfitting and improve the generalization performance of machine learning models.”
This question is likely asked in an NVIDIA Data Analyst interview to assess your ability to manipulate data structures and implement efficient algorithms. NVIDIA values candidates who can optimize processes and think critically about data management.
How to Answer
One trick we can use is to record the attached indices for each value and then sort the values by order, we can then compare the new indices against the old indices. This allows us to then throw out the values that would be decreasing and outliers.
Example
“To solve this, I would track each element’s index while iterating through the array. Then, by sorting the values in descending order, I can compare each element’s position with its original index. If an element appears out of order, it should be removed to maintain the decreasing sequence. This approach ensures that the final array only contains values that are in continuous decreasing order, efficiently filtering out any that don’t fit this criterion.”
This question might be asked in an NVIDIA Data Analyst interview to assess your understanding of natural language processing (NLP) and machine learning methods that can be applied to real-world problems.
How to Answer
When answering, start by outlining that the problem can be tackled as a classification task. Briefly mention supervised methods, like training a classifier on labeled data to predict the best match, and unsupervised methods, such as using keyword search or word embeddings to measure similarity. This shows you understand both approaches and their applications.
Example
“In tackling this problem, I would approach it as a classification task. For a supervised method, I could train a model using past user inquiries and manually labeled responses to predict the most relevant FAQ. Alternatively, I could use an intent-based system where questions are classified based on their intent to find the best match. If we don’t have labeled data, an unsupervised approach could involve keyword searches or using word embeddings to measure the similarity between the user’s query and FAQs.”
