First aptitude test including coding questions.
Then one HR interview round where there are questions like where do you see yourself in next five years, what are your hobbies and why do you want to work in Walmart
Three questions were asked, 20 , 30 and 50 marks. The questions were from greedy, dynamic programming, and binary trees. The first question could be solved through brute force, but for the rest an optimized approach was required.
It was a recorded interview where you speak into the camera and answer behavioral questions. It is easy to practice for before and you get unlimited attempts to record yourself, which is rare.
