I applied online and heard back from a recruiter within a week to discuss the role. The next step was an introductory video call with a Senior Engineer to dive into my background and motivation. Following that, I completed a technical round involving two algorithmic questions. Then a standard background check. If you pass, you get invited to a 3-day work trial in Denver. The team is honestly amazing, super talented and really friendly. Working with them was the best part of the experience. However, for international candidates (especially from Chile/LatAm), it is crucial to know that the logistics are high-risk. You are solely responsible for booking and managing all your travel arrangements (flights, hotel, transport) entirely on your own. You must have around $3,000 USD available upfront to cover expenses, as reimbursement happens only after the fact. The work trial itself is unpaid (at least for international candidates). I was also informed upon arrival that the historical pass rate is quite low (around 30%), and in my case, the timeline to design and build the solution was unexpectedly compressed from three days to two. Feedback is also not guaranteed if you don't get the offer. It’s a great technical opportunity, but weigh the financial risk and logistical effort carefully before flying out.

The interview process consisted of four stages. First, I had an interview with the CEO, followed by two technical interviews. The first technical interview involved solving a coding problem. The second one included another coding challenge along with a presentation, where I was asked to showcase two projects I had worked on. The presentation was very open-ended, with no strict requirements other than presenting something I had built and felt proud of. After passing these stages, I was invited to a work trial. The company covered my round-trip flight, accommodation, and meals in Denver (I am based in Chile), although the days worked during the trial were not compensated. The work trial lasted three and a half days: I worked on a project for three days, and on the last day I gave a presentation about what I had accomplished. The response time between the first three interview stages was quite fast, usually within one or two days after each interview. I received the final decision on the evening of the last day of the work trial. Overall, the experience was positive. Everyone I interacted with was very kind and respectful, which made the process pleasant. One area for improvement would be feedback: during the second and third stages, there wasn’t much opportunity to understand whether I was meeting expectations or what I could improve for the next step. Regarding the work trial itself, I would say it was a good experience, with consistent check-ins and support around the project I was working on. One point I noticed, which I’ve also seen mentioned in other reviews, is that throughout the process there was frequent emphasis on working long hours. While it’s understandable that startup environments can be demanding, repeatedly highlighting this can feel a bit intimidating, especially since work-life balance is important to most people. Rather than promoting long working hours as part of the culture, it might be more beneficial to focus on internal efforts to keep workloads sustainable.
