• No public code samples, open-source contributions, or recent commit history

• Generic answers about previous experience (we will ask for specific systems, metrics, teammates)

• Resume keywords copied directly from job description language

• Timezone inconsistencies or unexplained delays in live video scheduling

Bonus Points

• Experience with AI/ML integration, OpenAI API, or LLM tooling

• Familiarity with infrastructure-as-code, CI/CD pipelines, or observability stacks

• Interest in new tools like LangChain, Bun, or edge functions
