Walmart Global Tech Sr. Software Engineer interview questions

Typical tech loop... 30 minute recruiter phone call to align and get your salary range. One 45 minute technical screening with coding. One 45 minute session for system design. One 45 minute session with the hiring manager (actually one level up from direct manager, I think director or whatever they call it to manage multiple teams). They declined to give me an offer. But then I had someone else reach out and schedule a 30 minute video meeting for another similar position. It was an internal recruiter. They did not log onto the meeting. They did not respond to a "hey you're 20 mins late" email. They completely flaked and ghosted. That's super unprofessional. I bet they realized they scheduled it to someone who didn't get an offer recently but then just ghosted instead of backtracking in a tactful way. But it's disrespectful.
