Are we doing an interview?

[Silverobama]

I joined a chat room and it was someone doing her livestream. I could use the microphone in my phone to chat with her. She kept asking me questions like an interview and I was a bit annoyed. I asked her: Are we doing an interview?

Is my italic sentence natural?

It's natural enough. You could also say, "Are you interrogating me?"

I joined a chat room and it was found someone doing her a livestream. I could use the microphone in my phone to chat with her using my phone mic. She kept asking me questions like as if it was an interview and I was got a bit annoyed. I asked her no colon here Are we doing an interview?

See above. Your question is grammatically correct but I'd probably be a bit more forceful/sarcastic.

Why are you cross-examining/interrogating me?!
So when do I get a chance to ask the questions?
