Phone interview, asked some Fermi question, number estimation questions, and probability questions. Each question was given 10s to 1min to answer. By the way, the questions are similar to those questions already on glassdoor.

Five Rings’ Online Assessment 19 questions, 2 or 3 minutes. Tests mental math, estimation, combinatorics, quick logic, and probability intuition—very speed-intensive. After finishing OA, I received rejection within just 10 minutes.
Online interview with HR person firing maths questions at me. Was unable to clarify on the questions being asked, so I don't think she understood the questions she was asking. Very frustrating experience
