This was an onsite interview. It included introductions, resume review, a warm-up algorithm question, and a system design question based on the team's existing architecture.
After introductions and a review of my resume, I was given a simple algorithm question as a warm-up. Then, the interviewer introduced the ML team's models, their inputs and outputs, and I was tasked with designing a system to connect these models. This involved detailing information flow, intermediate storage, and final storage formats.
During the design discussion, I was asked about trade-offs, such as why to use RPC instead of REST APIs for inter-service communication. The specific details of the architecture are sensitive, but the approach of building upon an existing system was a novel and interesting experience.
