DoorDash Legal Operations interview questions

I had the initial interview with the recruiter. My second round included two separate interviews from the hiring manager and a Senior member from the team. I thought the Seniors member went pretty good. As I spoke with the hiring manager, I felt like he was disengaged and quite rude. I wonder if he expected someone else of a different ethnicity. I was treated poorly. It makes this whole interviewing experience disheartening and potentially eroding the confidence in this job-seeking process.
