Epic interview questions

First step was a basic online personality/intelligence test. A week or so later, I had a "phone interview" which was really more of an informational, Q&A type chat. I then had to take some basic math, logic, and programming assessments. I had to do this at a local test proctor site. The last step was an on-site visit. It consisted of a software demo, tour of the Epic campus, more math and verbal assessments, and 1 on 1 interviews with a Tech Services employee and with an HR representative. They got back to me with an offer just 3 business days after my on-campus visit.

I applied for the UI/UX Designer position because of my programming education and prior employment as a medical software implementation project manager for an outpatient clinic using a competing software. I performed a personality test about how I would react to certain ideas/situations- very Myers-Briggs reminiscent. Then I was called by an HR rep who was very nice, but seemed nervous, and asked about my interest/skills. He said he would send me a design assessment, but attached the sheet with his interview notes on accident. The form was mostly empty although I answered the questions- the interests I had just spent an hour expressing, were missing... I politely pointed out his attachment error and promptly received the design assessment in response. I created a UI design mockup for a family history/personal history screen with some constraints on number of screens but unlimited time limit. I promptly returned the mockup assessment within 8 hours. Then, nothing. I tried to follow up with him several weeks later, once via email and once via phone, but no response. I had heard Epic prides themselves on clear contact with applicants. A friend of mine was able to ask another HR worker for him to call me so I could ask about their hiring status. The other HR rep said this was uncommon. My HR rep called, tried to break the ice a bit, obviously they hired someone else but when I asked politely about why I was not moved forward he responded "I could just tell by speaking with you" - very odd, then why give me a design test? ... I have the feeling he may have lost my designs and didn't know what to tell me since he took poor notes during the interview... If I performed poorly on the test, feedback would have been constructive. He handed me off to another HR rep so I could hear about information on other positions which I had expressed no immediate interest in. She didn't give me information, but instead began to set up onsite interviews and said I needed to prepare a short presentation for the interviews. I can understand why they would throw me straight into an interview for a different position, but I was talking to thin air. I sent her an email, after good consideration, that I was not interested- perhaps I could apply in the future for better fitting positions and that there had been some miscommunication about the interviews. She responded two weeks later, but at least she did respond. Overall: not impressed.
