I applied through Walmart Careers. The process was very quick.

The first round was a Webex interview. The questions were mostly focused on past experience, problem-solving, and some technical aspects of Java, Spring, and databases.

The second round was onsite, held in Washington D.C. This consisted of three separate rounds:

• One managerial round
• Two technical rounds

These focused on design-based questions related to Walmart's retail processes, along with smaller problems such as finding a missing number from an array and identifying palindromes in the most efficient way.

Design an e-commerce system where data comes from various retailers. The client should be able to compare prices of products.

Find the missing number in an array.

Find if a string is a palindrome.
