Unity Advisory interview questions

I had a call with their internal recruiter, then an interview call with their CTO, then I was offered interview days to choose from, which I responded to on the same day and got hosted with no confirmation or the promised interview prep info. I only received the confirmation and the prep in the morning of the interview! I asked to reschedule it as I wasn't expect it to take place on that day due to being hosted with no confirmation, also because I was given no time to prepare for the interview - they refused to reschedule. I went to the interview that had a coding task that is entirely in Python! despite the job description having zero (literally zero) mention of Python neither my CV of I ever claimed to be Python Developer in format 3 interview stages... I flagged this first thing in the interview and the interviewers assured me that it's not required and it will not be used against me in any shape or form. Then I got ghosted for another week, until I received an email from their recruiter apologising for delay and prompting that I'm still being considered and will hear back soon...and got ghosted until I reached out for an update after a week from that email (2 weeks since the interview) to finally receive feedback!... wait for it.... I was rejected about Python! and they are not even trolling.
