Ubisoft Senior Full-Stack Web Developer interview questions

All people were so friendly, I loved all of them; I passed the technical and behavioral interview very well.. the IT Director told me that I was able to answer a question that nobody else had answered! They actually ran out of questions because when I was answering one question I was comparing the language with other languages and comparing the feature in question with other features and so on. Then they gave me a task to do within only 48 hours, both a front-end and an API on the back-end, I worked on it continually during the two days.. I only slept about 5 hours.. I completed all the required features plus one or two optional features.. however.. after submitting the project I got a general mail of rejection after a few days telling me that they moved forward with candidates with that fit a bit more than me! I believe they are hiring only certain nationalities and colors and the hiring decisions are not actually based on what is happening in the interviews/tasks/etc. They were contacting me at the end of the grace period.. they contacted me after my application by exactly two weeks, at the end of the day.. and later they were emailing me on the last minute on Fridays.. etc.. so although the decisions are premade I think they make such interviews because they can't find a 'legal' reason to reject the applications. And at the end they hire people making really low quality stuff.. I believe this drives the senior serious programmers crazy and they don't understand why these people get hired! I think it is just yet another corrupted big company. This is really depressing.
