IQ / Intelligence Test
Interview
The first step in the process was to take an IQ test that consisted of everything from "which pattern would come next" to expected value problems to brain teasers. I was made aware that there is no pass or fail on the test, but that it would be used to gauge my problem solving skills. After completing the IQ test I had a first round interview. 30 minutes was technical: Mental math where you have 4min to successfully solve as many of the 30 mental math (addition, subtraction, multiplication, division and a couple what is xx% of 1200 for example), an expected value problem where I was asked to determine the expected value of 3 scenarios (you should have a good understanding of expected values and risk tolerance and deploying bankroll giving odds of winning.) And then finally I was asked how many pounds of milk cows in the US produce per year. The behavioral interview was straight forward with a few questions regarding collaboration and my personal trading.

I was sent an IQ like test with a focus on probability/trading problems. It was essentially 15 probability questions to be expected and 15 IQ test like questions. After submitting my availability to the recruiter, I get an email saying that my interview was that day. I was completely caught off guard and did not know what to expect. This round was all mental math which I was not prepared for at the time. If I had maybe a heads up, I would have brushed up on my mental math. Otherwise process was fine.

Take online assessment, got email for intro meeting with 2 people. First one was behavioral, second was asking a bunch of mental math probllems and market sizing question. Super day was super exhausting and all over zoom, the longest I have ever had to complete (literally 10 am to 6 pm). Included "shadowing" a desk, HR interview, a very random "technical" interview asking questions like why the sky is blue, and an odd case study.

Interview
Applied online through RippleMatch. Took an logic/probability test online (took an hour). First round of interviews was in three stages. The first stage was a market game with a group of other interviewees. They said it wasn't judged but it probably was. The next day there were two interviews, one with 4 minutes of mental math and then a case interview, and the other was behavioral.

The superday was next and was all on Zoom because COVID. I think they normally do it in person. There were 5 or 6 rounds of interviews and we were also introduced to one of the co-founders of the company and the recruitment staff. The interviews were a mix of behavioral, technical, and probability games.

You apply online, then you get a math test. If you pass, you are sent to Skype interviews, one behavioral and one technical. If you pass, you go on-site.
Interview Questions
You need to have above-average skills with market making. One of their group activities is market making. They ask you to make a market off of the sum of six die. Dice are thrown one by one and you can adjust your market each time it's thrown and trade on it. It starts off with offers to sell/buy being made only by the applicants, and if things get stale the interviewers step in with obviously low/high offers. You are asked to keep track of your position and your net profit/loss. If you don't do much they will call you out and ask why you're not trading.

I applied through Handshake and then was contacted. I then did a Skype call with a trader and HR. Then I went to the superday
Interview Questions
There really wasn't a difficult or unexpected interview question. We played a card game with betting, which was just using common sense and probability to estimate how much you would bet and the expected value of winning. Then There was a group interview with two traders and shadowing some of the traders to see the life. Then we did a market making game which was then again really really easy. Overall, basic probability questionss and I don't really have much else to say so now I'm just filling up space.
