Awful. Felt like I was being judged the whole time -- interviewers were rude and came across like they were the cool kids and you weren't. Even if they had offered another round of interviews, I would have declined based on my initial experience.

I had a brief call with the recruiter and then two calls with different team members. They sent me the list of questions they planned to ask before each interview, which was greatly appreciated and helped with my anxiety.
