Factual Software Engineer New Grad interview questions

45 min hackerrank (2 lc hard, 1 medium) -> phone screen -> onsite really difficult interview. probably the hardest i've taken this entire recruiting cycle. everyone there looks crazy smart and talented. definitely one of LA's best tech companies onsite was full day. had a nice wwelcome message in my interview room and everyone was friendly. i choked really hard on one interview which is what I suspect sunk me

I applied online and received a follow up email with an assessment link. The assessment was from hackerrank and I was ask to finish it in 45 mins. total 2 questions in my language choice. One was easy and the second one was medium to hard. I didn't prepare well on the second one so I think I only got 1.5/2 correct.
