I submitted my resume online, and the recruitment company called. I don't know how to ask for advice. What do I need to ask?

You just say, "Hello! Are you XXXX technology company? My resume has been submitted to your company. He will say, yes, I have read your resume before calling you. Just answer, can you tell me about my professional title and my treatment in your place? With this understanding, you can decide whether to go or not, and you can advance and retreat freely.
