Ubisoft 3D Artist interview questions

I was given a total of 3 interviews by Ubisoft over a period of roughly five months for different art positions. Despite saying I should expect them to get back to me soon, they ghosted me after each interview, only contacting me weeks to months later for the sole purpose of giving me an interview for a different position (which is how I would find out I didn't get the previous job). Needing a timely response after my latest interview (I was given an offer by a different company), I contacted them after two weeks and a half to do a follow up. Within less than an hour, I was given a reply that my application had been denied, and that they wished me luck. The recruiter I had been speaking with added that, coincidentally, he had attempted to reach me earlier that same day (which I find perplexing, seeing as I was told the exact same thing the last time I tried to contact Ubi, after a much longer silence of ~2 months). In my mind, I have no doubt that if I had not tried to reach the recruiter on that day, I would have never heard about my application again. Overall, I found the entire application/interview process with Ubisoft highly unprofessional, especially considering I've had no trouble hearing back from any of the other studios I've dealt with.
