I interviewed at hyperexponential (London, England)
Interview
Good. There's one HR round, then hiring manager, followed by a technical interview, and a final values round, the hr will prep you after each round and they respond pretty quick
Process was four stages but felt really helped through by the talent team - it felt like quite a relaxed process with frequent proactive check-ins after interviews, email updates and a warm welcome after joining. A really lovely group of people that make it a great experience.
Interview questions [1]
Question 1
Describe a situation that you felt genuinely challenged and out of your depth - how did you react.
I applied through a staffing agency. The process took 4 weeks. I interviewed at hyperexponential in Oct 2025
Interview
The interview process had four stages. First was an HR screening call to discuss my background and what the team is currently working on. After that, I was given an Excel-based model and asked to recreate it in Python, plus make a few extensions/improvements.
The next round was a discussion with two team members, mostly focused on how I approached the Excel-to-Python conversion (design choices, assumptions, validation). The final round was a conversation with the hiring manager.
The company presents itself as an insurtech, but in my experience the interviewers were transparent that they were not insurance specialists. Based on what they shared, a large part of the role seems to involve helping clients convert existing Excel models into Python. If you’re looking for a role with strong technical, quantitative, or insurance domain expertise or more advanced technical challenges, it’s worth clarifying expectations early.

Question 1
There weren’t many deep technical questions. Most of the discussion was about how I translated the Excel logic into Python and how I verified the Python results matched the spreadsheet. Overall, it felt more like a walkthrough of the case study than a technical interview.
Thanks for sharing such a clear summary of the interview process.
hx is very deliberately a melting pot. Some people join with deep insurance experience and grow their SaaS and engineering exposure. Others come in without insurance background and end up enjoying learning how our product shapes real-world decisions, from underwriting portfolios to things like launch risk for space missions. That mix is intentional and part of what makes the work interesting. And special!
As always, being clear early on what you want to learn and work on matters. Thanks again for sharing your experience, and hopefully our paths cross again.
