The recruiter reached out because my background lined up with what they want, and it felt obvious from the start that this team cares a lot more about ads domain fluency than generic big tech interview performance. I had a recruiter screen, a TTL cache phone screen, and then a five-round onsite with one coding round, two behavioral EM rounds, data modeling, and system design. The technicals were mostly straightforward if I could talk through tradeoffs, but the behaviorals were a much harder vibe check than I expected. I am still waiting to hear back, but the biggest thing I took away is that if I can speak confidently about how ads serving, demand, targeting, and capping actually work, they will forgive more than they would at other companies.” ## Related questions - [How would you design Perplexity's system?](https://www.aced.io/questions/6492/design-perplexity-system-architecture) - [How would you design a system like Google Street View?](https://www.aced.io/questions/7213/design-system-like-street-view) - [How would you design a travel booking app?](https://www.aced.io/questions/7393/design-travel-booking-app) ## Related courses ### [Software Engineering Interview Prep](https://www.aced.io/courses/software-engineering) ![Software Engineering Interview Prep](https://images.ctfassets.net/x78yjrjc11pq/4VkuYewBHUFIVUS5oJDW5h/02e833439b1289f25f38f13f81cbdca3/adobe_stock_optimized.jpeg?w=800&h=800&fm=webp&q=75) We help candidates prepare for software engineering roles at Google, Amazon, Microsoft, Meta, Apple, and other top companies through mock interviews, frameworks, and advice from senior candidates.
