Two Sigma Software Engineer New Grad interview questions

1st Interview - Technical phone screen (Medium leetcode question, passed) 2nd Interview - 4 round Technical interviews, - All were around leetcode medium/hard and did well on all 3 interviews but one of the interviews was the worst interview experience of my entire life. It was an extreamly racist man that wasted 30min of my time grilling me on behavioral questions (when this was strictly a technical interview and had a 3hr behavioral scheduled the next day) and giving back unnecessary, degradding and RUDE responses to my ans such as " I don't care about that". He left me with only 15min to solve a hard leetcode question and made it impossible for me to pass the interview. Reported this to the head of HR as it's not fair for my hard work to be thrown out the window simply because of ONE RACIST engineer.

This was the worst experience I had in an interview. The guy doing the interview didn't seem interested in providing any feedback or talking to me at all other than to give me the question. Halfway through he started typing on his keyboard doing other work and it was very distracting both in the noise and that he would be so disrespectful of my time to not even listen to me as I try to solve the problem he gave me.
