Choose an algorithmic approach that efficiently identifies and analyzes contiguous subarrays. Design a solution that involves manipulating the binary array to identify subarrays with an equal number of 0s and 1s.
Example
“ I’d approach this problem using a hashmap to keep track of the cumulative count of 0s and 1s. As I iterate through the binary array, I update the cumulative count and store the first occurrence of each count in the hashmap. The maximum length occurs when the same count is encountered again, indicating an equal number of 0s and 1s between those two positions. For example, given the binary array [0, 1, 1, 0, 1, 1, 1, 0], I would iterate through it, updating the cumulative count. At position 4, the cumulative count is 2, and I check the hashmap. Since I’ve encountered the same count before at position 1, the length of the subarray between positions 1 and 4 is equal, and it’s 4. I will continue iterating and updating the hashmap.”
At Walmart, understanding and identifying suspicious user behavior, such as vote manipulation, is crucial for maintaining a fair and secure online platform. This question tests the software engineer’s ability to analyze data and design SQL queries to uncover potential fraudulent activities.

“For identifying potential fraudulent behavior on the forum, I’d use metrics like the percentage of upvotes on a user’s own comments or patterns of repetitive voting. I’d design a SQL query to count upvotes, group them by user, and calculate the percentage of upvotes from the same user. This query would highlight users with suspicious voting patterns, aiding in the detection of multiple accounts created for upvoting. The query would consider user IDs, comment IDs, and upvote timestamps to analyze voting behavior effectively.”
This question tests your ability to design efficient data structures and implement fundamental operations. Being a software engineer at Walmart, these skills are important for creating data structures with specific functionalities.
How to Answer
Choose an algorithmic approach that allows for efficient implementation of the required operations. Design the stack structure, ensuring it meets the criteria of supporting push(), pop(), and constant-time retrieval of the minimum value.
Example
“To create a stack supporting push(), pop(), and constant-time retrieval of the minimum value, I’d use an auxiliary stack to track minimum values at each step. When pushing, I’d compare the new element with the current minimum and update the auxiliary stack. Pop operations would synchronize with the auxiliary stack. This approach ensures constant-time retrieval of the minimum value during sequences like (3, 2, 4, 1), maintaining efficiency using only the stack data structure.”
At Walmart, data-driven insights are crucial for understanding user behavior and optimizing systems. Hence, software engineers need to demonstrate their proficiency in extracting relevant information from large datasets.

Example
“To count daily active users on each platform from user logs for the year 2020, I would select log_date
, platform, and use a COUNT(DISTINCT user_id)
with a grouping by log_date
and platform in a SQL query on the user_logs
table. Filtering logs based on the condition that the year extracted from log_date
is 2020 ensures a focus on that specific year, providing a concise way to analyze user engagement and obtain valuable insights for data-driven decision-making.”
Software engineers are expected to showcase their ability to design a program that checks specific conditions within a given dataset. At Walmart, efficient and accurate handling of data, including strings, is essential for various tasks, such as processing customer information.
How to Answer
Choose a straightforward algorithmic approach to check whether all characters in a string are the same. Write a Python program that implements the chosen algorithmic approach, iterating through each string in the list and performing the necessary checks.
Example
“To create a Python program to check if each string in a given list has all the same characters, I’d use a simple approach. I’d iterate through each string, comparing each character to the first one. The program would return a list of boolean values indicating whether each string meets the condition. The code might look like:
def check_same_characters(strings):
return [all(char == string[0] for char in string) for string in strings]
The time complexity of this program is O(n * m), where n is the number of strings and m is the length of the longest string, due to the need to compare each character of each string in the worst-case.”
