I had an initial call with a recruiter. It went super well and she was excited for my candidacy. I then had an hour long call with a member of the product team. She was very nice and that went well, too. I was then given a case study. I spent a few days working on it and I really liked the prompt. I interviewed with 3 PM's who I immediately felt were did not like me. I definitely felt unsaid biases from them based on my school/background/maybe appearance or race? I knew they didn't like me the second I started speaking due to body language and facial expressions. Regardless, I presented and answered their questions. I wrote the interviewers a quick Slack message thanking them for their time but that was ignored. I got rejected generically a few days later. Some feedback would've been nice given that I had spent hours and hours on a complicated case study
