Annapolis Internal Medicine interview questions

I was contacted initially through an email, followed by another email through another email address that was secured. I replied to the email that was sent through another job search engine, and the second email I was unable to open at all, it was asking me for log in information that didnt exist because I had never logged in before. I waited for a response to my first email, but never received a reply. Due to the technical issues of the second email, I contacted them and was able to get in touch with the HR representative that contacted me for an interview. I scheduled an interview for the next morning. They requested that I complete an assessment prior to my interview. I did so that evening. That morning I woke up to a missed phone call stating that my interview had been canceled because the HR employee had to sit in on a meeting that day and would be out of the office the following day, and they would like me to call back to reschedule the interview. By the time I received this message it was only about 30 minutes after it had been left. I called back immediately, left a voicemail, and followed up with an email as well. I never recieved any communication after this. I would have rather had them contact me and communicate that they either hired someone else, or they had second thoughts about me being the right candidate to interview over them leaving me in "limbo"...
