I applied through a recruiter. I interviewed at Aspect Capital (London, England) in May 2022
Interview
Take ages to respond/do anything.
Give you 2 weeks to complete a simple coding task then take another 2 weeks to respond after you do it 1 weekend...
First interview was split into 2 stages with 1 person that said/did very little and was pretty much just a silent observer judging
Interview questions [6]
Question 1
Make a mapping function. takes a function as input (e.g. plusOne which adds 1 to the input) and runs it on all elements
Make a thread safe class that you can add prices to as well as retrieve prices from. it also wanted a way to check whether the price had changed since the last check (have to store price each time you look it up for this)
Technical test, then a 2 hour in-person interview. First hour focuses on going through the test and coding questions and the second hour of the interview focses on system design.

Question 1
Draw high level design of previous system worked on
Pleasant first stage interview, informal chat about the role and a bit about CV and experience. Second stage was an online coding test based on the kind of problems you'd encounter on the job and was given the promise I would get the chance to explain my approach and choices in the next stage. Provided neat, concise code that passed all edge cases and was rejected with the reason that "they didn't like my coding style". Deceptive interview process.

Question 1
HackerRank question was custom made for the role (not a generic set of questions to test algorithm knowledge that a lot of companies throw out when they don't know how to interview someone in tech).
