Based on the recruiter's email, I was expecting the conversation to include questions around my C++ coding skills and prior experience relevant to the role, and LeetCode-style coding in C++.

However, the discussion only focused on the hiring manager’s internal team architecture, more like an advanced system design deep dive of their current implementation, and I was told that my background was not at all related to the role.

The questions also felt more aligned with someone already embedded in the team, rather than a first-round screening focused on evaluating core skills and fit. It was a bit unexpected, as most senior-level interviews I’ve had (including ongoing processes with other FANG companies) typically follow a structured progression through coding, system design, and behavioral rounds.
