老外问我以前曾经是否在国外工作过是什么暗示？

您可以这样回复老外：

Dear {名称},

Thank you for your interest in our products. I have not previously worked for a foreign company, but I am fluent in English and have experience working with international clients.

I look forward to hearing from you about pricing and I am available to answer any questions you may have.

Best regards,
