Software Engineer Interview Experience - London, United Kingdom
Process
I went through the process via a recruiter. The process was long, I had 3 technical interviews and a meeting with the hiring manager and I believe I skipped a technical interview stage as I told them I had other final stage interviews that I would be hearing back from quickly. While the process was long, they were responsive and moved me onto each stage relatively promptly (3/4 weeks elapsed time I think). They cancelled and rearranged interviews on 2 occasions.
All of the technical interviews were 90 minutes long!! In each of them we discussed my background / technologies I had used, followed by questions about the technology they would be using (Python and Linux in my case) and finishing with a paired coding exercise. The coding exercise was low pressure which was good and all the problems were relatively straightforward (LeetCode Easy/Medium). The chat with the hiring manager was 45 mins long and we discussed my background, ongoing projects and a chance to ask questions.
All feedback throughout was really positive (from my recruiter) and the chat with the hiring manager felt great. I was then not offered a role and despite asking, given zero feedback.

Squarepoint Capital Work Experiences
- 5.0Growing firm, good colleaguesSoftware Engineer • Current EmployeeLondon, United KingdomJuly 11, 2025Pros: Squarepoint has clearly done very well over the past few years and is consistently growing and expanding as a result. That means a lot of career opportunities, and an environment that's anything but stale. I've noticed a lot of new faces showing up around the office recently, and there's a good positive culture emerging in the engineering teams - casual conversations at lunch, mid-week beers just outside the office on a sunny day, general camaraderie. Colleagues are very skilled. The cynical politics you might sometimes expect at a HF are not present, at least among the software engineering lot. Working here has been fantastic for my career.Cons: Big growth means growing pains. There's some clear technical debt that needs paying down across some of the firm's systems, which becomes more obvious as scale increases. Not everyone's experience is the same. For better or for worse, different teams can have quite different management styles. Expectations are high. People who struggle can be left feeling exposed; despite the growth, there's clearly a culture of not accepting mediocrity.
- 2.0Stressful environment with no diversitySoftware Engineer • Former EmployeeLondon, United KingdomJanuary 21, 2024Pros: The team has very knowledgeable developers. It is a well-organised team with documentation and progress tracking. There are good progression options.Cons: Zero racial diversity and almost no women on the quant/dev side. Many unexpected layoffs, leading to many re-orgs and team shuffling. No work-life balance (although my manager was among the better ones about this). Poor compensation. Upper management mostly speaks French, and they often cannot express requirements in English.
- 2.0Micro-management and no transparency (might be only in my team)Software Engineer • Former EmployeeLondon, United KingdomAugust 17, 2023Pros: Friendly colleagues, decent office, free lunchCons: - During my probation period, the 2-level-up manager kept influencing product definition, system design, timeline estimation, and code implementation. An astonishing phrase from him: "I can do it within 2 hours". - We had 4 backend engineers and 3 front-end engineers working on the same project. We were delayed for one month (the manager defined the deadline). Even though the 2-level-up manager said it was no one's fault, I got punished in the end without any conversation.
