Was reached by a staffing company working with Walmart. Had an initial in-person screen. Was given a coding challenge after that to complete in a week and submit via GitHub. Very unprofessional response - accused me of copying code from someone else. It's a medium-level problem; they don't understand that there could be only too many ways to solve it and it's not unusual for people to have similar approaches to solve it. Very unprofessional, didn't expect such accusations from a company like Walmart.

Coding challenge - Ticket Service.
