把分角色对话粘贴到这里。角色用「面试官:」「候选人:」或「A:」「B:」「Interviewer:」「Candidate:」开头，AI 会自动拆分并带练。
面试官: Tell me about yourself. 候选人: I'm a product manager with 5 years of experience in the tech industry. 面试官: Why do you want to join our company? 候选人: I admire your data-driven culture, and I believe I can create real value here.
支持你那种「分角色」PDF（如 100 期外企面试库）。上传后浏览器自动抽取文字、拆分角色。
