Amateur hour and some minor red flags. Aside from the traders, there's perhaps not a single person in Akuna who's traded a security. They have a very restrictive compliance policy that bans trading. I've been trading options and other securities for the last 7+ years and follow markets daily, and they basically dissuades anyone like me who makes money from trading and has practical experience with markets. That suggests that the only ones working there are dispassionate about markets and/or have a very academic view of markets.
The team is very new. I asked the team couple of basic questions on how they manage risk, and they started to look uncomfortable and dismissed it saying, "looks like we're out of time."
As someone who's built technology for traders and someone who trades, they didn't ask me anything trading related. I've had various other interviewers where I was asked about this. It was just bunch of sophomore tech questions, followed by having you solve a leetcode-like question.
And they have a real-time, mission-critical application written in python. They said they're trying refactor this as it's falling minutes behind (wtf?). I asked why not write in C++? They said no one in that dept knows C++. As a C++ and python developer, I offered to rewrite it for them in under 2 months, but still, no offer. Clearly, your economic value to them is measured in how well you do on their leetcode.
The position I applied to was remote, but I was asked repeatedly whether I was open to relocation. That tells me that this is may not be remote in the future. And I had 2 other offers in hand, which were standard salaries for someone with my experience, but they said they may not able to match.
Anyway, I wasn't serious about joining given their compliance policy, but it was a good learning experience and I was able see what's like at a "professional" trading firm.
