on the phone

Hi everybody
I have to take the interview on the phone.
I think interviewer will introduce himself.
How can I greet him?
I think I can not greet like that " nice to meet you".
And how can introduce myself?
"I am Green"
or
"This is Green"
Which one is correct?

It really depends on the type of interview. No, I wouldn't say "Nice to meet you." as you're not meeting him. You could go for "How do you do?" but only if it's kind of formal. If it's informal, we'd usually skip this kind of greeting. I'd say "This is Green."

-This is Joe Johnson from BBC and I'm calling in regards to the job application that you dropped off at our Downtown location.
**Hi, how are Mr Johnson. I'm really happy to hear from you.
-I'm fine, thank you for asking. I was ......your resume and ......
