What are some integral questions you would ask an IO program you are looking into?

I'm spending the next month researching different IO masters programs. I'm going to email the heads of the programs to introduce myself and ask some questions.

What would you be sure to ask that also couldn't be easily viewed on their program site?

Also, would it be a good idea to attach my resume in the email, and if the conversation goes well, ask to meet with them in person? I wasn't sure if that would be both unnecessary and too forward.

Thanks so much!
