Technical Depth and Current Knowledge Questions

Assessment of a candidate's deep technical expertise and up to date hands on knowledge across core engineering domains. Interviewers will probe system design, performance optimization, distributed systems patterns, databases both relational and non relational, caching strategies, messaging and queuing systems, application programming interfaces, cloud infrastructure, observability and monitoring, and relevant programming languages and runtimes. Candidates should be prepared to discuss concrete technical trade offs, debugging and performance tuning approaches, how they research unfamiliar topics to maintain accuracy, and examples of technical decisions they have owned. This topic covers maintaining current technical fluency even in leadership roles and being able to have rigorous technical discussions about architecture and implementation.
