I applied online. The process took 2 months. I interviewed at Five Rings in Jan 2021
Interview
The interviewer was not able to describe the problem clearly, and I can see from his face that he becomes impatient from the first minute. I've passed the first 5 rounds and fail the 6th round. The problem is not super difficult, but the interviewer is terrible.
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 assessment on probability questions. Each question has either 2 or 3 minutes limit. After that I had a short HR call. Did one technical round with a researcher who asked me about algorithm.
Interview questions [1]
Question 1
HR said the tech interview will be on probability but being asked algorithm.
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
