I applied through college or university. The process took 4 weeks. I interviewed at Five Rings (Boston, MA) in Oct 2017
Interview
It'a first-round phone Interview. There are basic behavioral questions for salary and estimation and calculation questions. The question types are similar for everyone. It's really hard to get the estimation questions right.
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
