Acciona UX-UI Designer interview questions

I was invited to complete a one-way video interview, which was advertised as taking around 10 minutes. In reality, the process required considerably more time once preparation, recording, and reviewing responses were included. What disappointed me most wasn't being unsuccessful, but the lack of communication afterward. It's now been over a month with no update or acknowledgement. I assume I wasn't selected, but a simple rejection email would have demonstrated respect for the time candidates invested. One-way interviews are already a fairly impersonal hiring method. Combined with complete silence afterward, the experience felt dehumanizing and left a negative impression of the company's recruitment process. I hope Acciona improves its candidate communication by providing timely updates, even if they're automated.
