Overall Process: The process consisted of multiple rounds including a technical coding round followed by a system design discussion. Technical Round: The coding round covered: Implementing a basic mock of an Elasticsearch-like system (indexing + querying concepts) Classic problem: Product of array except self System Design Round: This round was not upto the mark with a typical system design evaluation. Instead of discussing system design concepts (like scalability, architecture, trade-offs, etc.), the interviewer focused primarily on language-specific questions in golang such as: what is the role of Go's built-in testing package? Explain how function calls work in Go What are the key differences between value types and reference types in Go? These questions are more suited for a language fundamentals round rather than system design. Feedback / Observation: The structure and intent of the system design round felt unclear.
