Epic Interface Analyst interview questions

I got a mail from an Epic Recruiter asking me to apply for the interface Analyst position. I applied and received a follow up to take the personality test online. In a couple of days I received an invite for a phone interview. The interviewer called on the scheduled time and was a very friendly and accommodating person to talk to. The interview was a casual discussion about my previous experience and the kind of a job I looking for. I was pretty much confident of getting to the next step in the process and in a couple of days received a mail from HR person regarding scheduling an on site interview at the Epic HQ at Madison. I am scheduled for the interview next week. Hoping to get through this final step.

Submitted the resume through website. Got a mail to attend the phone interview. It was okay. Waiting for the response from them.
