I applied online. The process took 3 weeks. I interviewed at AKUNA CAPITAL (Boston, MA) in Oct 2019
Interview
Online HackRank Test. 5 questions, 2 hours. 3 Easy / Medium, 2 Hard. Got 4/5 correct and received an invite for a phone interview. Interviewer was very friendly. Asked brief resume questions followed by three fairly easy probability questions. Felt as though interview went well as I correctly answered questions. Received reject email a week later.
Interview questions [1]
Question 1
Let X and Y be random variables with standard deviation a and b. What are the bounds of Var(X + Y)? Pile of 100 coins, 99 fair 1 double heads. Pick random coin, flip 10 times, get 10 heads. What is the probability the coin is double headed coin? Dice sum games.
Warning: Some of the interviewers ask for proprietary info about how you trade or construct signals, either by asking detailed follow-up questions far beyond common knowledge, or by asking you to find patterns in market data that would inform a trading strategy.
This is quite different from assessing your skills as they're seeking new ideas which can be monetized. So if you're an experienced candidate, don't bother applying to Akuna unless you want to give away knowledge and waste lots of time with no real prospect of a job offer.
If you must interview with them, don't disclose proprietary info, but instead describe signals or methods that are commonly known or don't work well.
received a test link having 3 easy python programming problems. fairly straightforward, qualified to the next round. the next one was 7 probability questions you get 5 minutes per question to explain your solution and tell the answer. the questions were standard, it was a vidcruiter round. i messed up slightly on the first question, and might not proceed to the next round.
