Walmart Software Developer interview questions

This was a terrible experience overall. Very poorly orchestrated interview process right off the bat. I was directly contacted by the hiring manager for a phone screen. A week later the recruiter informed me that I was invited onsite for 6 interviews (1 hour each) After spending the whole day onsite the hiring manager let me know I'd know the outcome the next day. However, the next day the recruiter asks me to come back for 2 more interviews onsite; no explanation for why, with whom, etc. Very rude communication and no attempt to accommodate with the timing either. One would assume they would structure the interview panel to include all interested teams in the 1st place, not keep calling a candidate back for additional team interviews. Anyway, after spending 9 hours total (including 1 hour over the phone), these guys didn't even have the decency to get back with a response or follow-up: it's been over a month. Really disappointing process and interactions. I will obviously never interview with them again and would actively encourage my peers to never interview with them either.
