What should I say? Leaving a message?

I would say "Hello, this message is for Mr. Pat or Joe Monahan...." and then so on...

Just my opinion. :-) Good luck with the internship.

My name is Your Name, and I was calling to speak with Joe Monahan or Pat Monahan regarding an internship with Company Name. As you're out of the office at present, I'll try back another time. In the meantime, you're welcome to check out my work at yourwebsite dot com. Thanks.

(Obviously the last part may be irrelevant, but it's a pretty good idea to mention just one of your many wonderful qualifications.)

*I wanted to add that it's important to be brief. As a former receptionist, I can tell you nothing makes a poorer impression than a rambling message or one that goes on long after the salient information has been communicated.

Hope that helps. Good luck.

Greet each man separately (Hello, Mr. Monahan and Mr. Monahan...) as if they had different last names and leave a message about what you are looking for then state you will call back. That gives them a heads up that you are looking for an internship and if they need any information, they can get it ready.

Hello Mr. Monahan. My name is............. and I am interested in securing an internship with your company. I am......years old. My education consists of............ My phone numbers are:

Looking forward to hearing from you.

Thank you for your consideration.

You could say Monahan Bro.s, you could also say your name and number and when to expect your next attempt. Hope this helps :0)

"Hi, this message is for Joe Monahan, my name is XXX and was sent to you by XYX for an intern position, I was wondering what would be a good time to meet you or to give you my resume, please call me back at your earliest convenience. Thank you very much!
