instalilyAI·AI Engineer·Take-home Assignment

Jun 2026
instalilyAI gave me a 48-hour take-home for an AI Engineer role and it was a lot more involved than I expected. You're basically building a full product from scratch: scraper, backend, agent, frontend, all wired together and working end-to-end.
  • Build a complete AI agent chat application within 48 hours. This includes writing a custom web scraper to pull product data from an e-commerce site, building a backend and frontend, and wiring an AI agent that can answer user queries grounded in the scraped data.

“The scope of this thing did not fully register until I was about six hours in and realized the scraper alone was going to eat most of my time.”

instalilyAI·AI Engineer·Onsite - Coding / Algorithms

Jun 2026
Onsite live build round at instalilyAI where you have about four hours to ship a working fullstack AI app from scratch, including web scraping and AI-driven processing on the scraped data. Less about algorithms, more about whether you can actually deliver something end-to-end under real time pressure.
  • Build a complete fullstack AI application from scratch in ~4 hours. It should include web scraping, AI-driven processing of the scraped data, and a working frontend plus backend.

“Four hours sounds like a lot until you're twenty minutes in and still arguing with yourself about folder structure.”

instalilyAI·AI Engineer·Onsite - System Design / Architecture

May 2026
The final stretch of the instalilyAI onsite was a live demo and Q&A on an AI app you built earlier that same day, which is a brutal format if anything in your build went sideways. Less about polished answers and more about how you hold up when things aren't clean.
  • Walk us through the design decisions you made while building the AI app today.
  • What are the architectural limitations of what you built, and what would you change with more time?
  • How did you handle the parts of the app you didn't finish in time?

“This is where I felt the pressure most.”

instalilyAI·Software Engineer·Executive / Final Round

May 2026
Short phone call with a founding engineer at instalilyAI that snuck in after I thought the loop was already done. Three behavioral questions plus a segment where you're supposed to ask them things, which I was not ready for.
  • Behavioral question asked by the founding engineer during the call (one of three).
  • Reverse behavioral segment: what questions do you have for the founding engineer about the role and company?

“The content doesn't spell out what the actual questions were, just that there were three behavioral ones.”
