I applied online. The process took 2 weeks. I interviewed at Five Rings (Nashville, TN) in Dec 2017
Interview
It was a technical interview with a few CS problems designed to see how the interviewee would approach solving these certain problems. If I recall correctly, computational complexity, such as whether some approach was in O-linear time or O-exponential time, was stressed quite a bit.
Interview questions [1]
Question 1
The interviewer asked me to design a way of searching for finding out if some number in an integer array was a sum of two other numbers in the array.
I completed an online assessment that consisted of some coding questions in C++. The contents of the questions were relatively straightforward, though there were a couple edge cases. I received a rejection email after submitting the OA.

C++ programming question involving data structures
I applied through a recruiter. The process took 2 months. I interviewed at Five Rings (London, England) in Nov 2020
Interview
15 minute recruiter video interview.- CV questions, career aspirations, motivation.
1 hour technical video interview - implementing a well-known data structure.
5 hour virtual onsite round - 4 technical interviews (data structures, algorithms) and a chat with the CTO.
Could choose what language I wanted to code in (I chose Python).
Technical interviews were not like LeetCode (apart from one LeetCode easy/medium). They were similar in style to Jane Street's.
