r/csMajors on Reddit: Karat Interview: Senior Data Scientist at Walmart
May 6, 2023 -
I have an upcoming interview at Walmart for the role of senior data scientist.
The interview is a Karat assessment, but I am not sure what the live 60 minute coding session would be like.
Should I expect standard leetcode medium questions or would it be a data science based interview?
If you could share any information, that would be very helpful

I did the data science intern one, and it was 10 minutes of stats questions (mix of multiple choice and open ended) covering things like probability, distributions, and confusion matrix, 10 minutes of ML questions such as which model do you use, cross validation, etc, and then leet code style questions. I only got 2, first one was easy-medium and second was medium. Interviewer kept rushing me tho, most likely since as 3rd party interviewer they need to go through as many questions as possible. For senior data scientist, probably much more in-depth stats/ml questions.

r/DataScientist on Reddit: Walmart Data Scientist 3 interview
February 16, 2025 -
Hey everyone,
I’m interviewing for a Data Scientist 3 position at Walmart and wanted to get some insights from anyone who’s gone through the process recently.
What can I expect in terms of:
-
Number of rounds
-
Technical depth (SQL, ML, Python, case studies?)
-
Business-focused questions or product thinking
-
Behavioral rounds (culture fit, leadership-style questions)
-
Anything specific to the DS3 level vs DS1/DS2?
Would also love to hear about any tips, topics to focus on, or experiences (positive or challenging). I’ve heard the interview might touch on both data science depth and how you apply it to business problems at scale.
Thanks in advance — really appreciate any info you can share!

For this interview, get ready to do Python + ML + Open-Ended Case Studies. Also, be ready for product metrics type questions, like key KPIs you'd use that are both technical (for a ML type problem) but also more business-y KPIs for a more analytics focused business question. Read Ace the Data Science Interview chapter on ML + Product Sense + Stats to get ready for the interview, and can solve SQL/Python questions as well on DataLemur (they have a few real ones coming from Walmart on the site already).

Interview includes around 4–5 rounds: a recruiter screen, technical assessment, technical interviews, a case study, and behavioral rounds. It tests your ability to apply data science to business problems at scale. Compared to DS1/DS2, DS3 expects more leadership, deeper ML knowledge, and strategic thinking. Prepare for complex SQL queries, ML system design, and product-focused questions. Practice on platforms like StrataScratch, LeetCode, and Kaggle.

November 27, 2024 -
Hello,
As the posts suggests I am completely lost on how to prepare for this interview. My SQL skills aren't the best but I still want to give it my all for this interview. Can you all please advise me on how to go about preparing? Any resources, any links, anything for me to get started? Feeling hopeless in this job market but still trying. Thanks a ton! :)

Focus on sharpening your SQL skills immediately. Walmart's data analyst roles often involve complex queries and data manipulation, so prioritize practicing SQL exercises and real-world scenarios. Platforms like LeetCode, HackerRank, or SQLZoo offer great practice problems. Also, familiarize yourself with Walmart's business model, their data-driven approach, and recent initiatives. Be ready to discuss how you'd apply data analysis to solve retail-specific challenges. Don't underestimate the importance of showcasing your problem-solving abilities and business acumen. Prepare examples of how you've used data to drive decisions in your previous roles. Even if your SQL isn't perfect, demonstrating strong analytical thinking and the ability to translate data insights into actionable recommendations can set you apart. Consider using AI mock interview to practice answering common data analyst interview questions. I'm on the team that created it, and it's designed to help you navigate tricky interview scenarios, especially when you're feeling uncertain about your skills.
