I applied through a recruiter. I interviewed at Boosted.ai (Toronto, ON) in Feb 2026
Interview
Given their unique interview process, it seems they've managed to build their ingestion and API services using nothing but algorithms you'd find on Leetcode. Don't make the same prep mistakes I did by spending 10 years developing distributed backends and optimizing OLAP databases.
Interview questions [2]
Question 1
Build a simple API to retrieve aggregated metrics with optional filtering, pagination, and aggregation. Just kidding! Solve this leetcode problem about strings.
Consider a query layer for a lakehouse with properties [x, y, z...]. What partitioning strategies do you choose and why? Distribution strategies? Just kidding again! Please solve this leetcode problem about a matrix inside another matrix...
