The interviewer was quite unreasonable — he insisted me to write a prompt for a complex use case without even providing the input files. Despite my efforts to walk him through the approach and the key points I intended to address, he kept pushing me to just write it in the call. To make it worse, he was nitpicking spelling errors — a position is better suited for an English teacher, not a GenAI Engineer whose core value lies in system design, logic, and prompt strategy.
