Questions posées lors d’un entretien d’embauche pour Senior Frontend JavaScript Developer chez Webtrekk

I got an email from HR asking to fill some basic HR questions after that I was given a coding challenge about writing a simple web application. A Basic CRUD for customers to do in a week. After I submitted the solution, I never received any reply not even when I submitted the solution as a confirmation. In other words, they just made me waste my time.
