Applied at Walmart for Software Engineer III

I am preparing for a set of three in-person interviews with Walmart for a Software Engineer III position. The interviews are scheduled for next week on the 9th, and I will be flying to Arkansas for them. The first interview will focus on programming and logic, the second will be a systems design interview, and the final one will be behavioral. I'm reaching out to see if anyone has experience with these types of interviews at Walmart and could share insights on what to expect, particularly for the programming and systems design interviews. Any advice would be greatly appreciated!
