I initially stumbled upon the Epic booth at my university's career fair during my sophomore year's spring semester. By the way, Epic strongly believes in standardized tests like the SAT and will definitely ask about the tests you took.

I gave them my resume, completed their online application form, and then got an email the next day inviting me for the on-site skills test.

The test lasted for about 3 hours and had 3-4 programming problems where you can use any major programming language (you don't have to solve them if you are not applying for a technical role). It included questions about a made-up programming language (aiming to test your ability to learn new things and apply your knowledge), math questions, logic questions, and a 1-minute math section.

I might get some details wrong as it was a while ago, but there is enough information about Epic's skills test anyway.

Then, I was told that there were no positions available at the moment and I should apply during the Fall semester, as they hire most interns then.

During the Fall semester, Epic came to my university's career fair again, and they actually contacted me through LinkedIn a couple of days before the fair. I applied through their website again and took the on-site skills test again. The test had the same structure but different questions.

Then, a week later, I got an email saying that the next step would be a phone interview with a software developer.

The phone interview, however, did not contain any technical questions. We talked more about my past projects and interests, and I had a chance to ask questions about Epic. I asked about their immersion program (which is when Epic's software developers travel to hospitals to see how things really work there so that they can write better software) to show that I was so interested in Epic that I had done some research. I think she liked that.

Another week later, I got an email inviting me to their headquarters in Madison, WI. I was also informed that one of the two interviews would be with a software developer and that I would briefly present a project I am most proud of or find most challenging. They also told me that I must be ready to answer some questions about the project and that the whole interview would take about 30-45 minutes.

Epic also asks you to bring your university transcripts and a list of three references to the interviews. In addition, I completed a personality test online before coming to Madison.

They paid for the flight and hotel, and my experience in general was great, as I was treated really well and the interviews were not stressful at all. I got a lot of information about what software developers do at Epic and had many chances to ask the developers anything I wanted during two group sessions with the actual developers, both completely informal, and you are not evaluated or anything.

I had only two interviews. The first one was with a developer where I presented a project I worked on in the past. You should really prepare for that, as a developer would be asking all sorts of possible questions.

My second interview was with HR. We started with questions about the reference list I brought with me. She asked who of those three people knows me the best and why, what positive things he or she might say about you, and what could be some negative things mentioned.

Then there were a lot of questions like: Why Epic? What do you like about our internship? What do you don't like? What are your other options? And how would you choose which offer to accept if you had several (like what factors are important to you)?

Then, a week later, I had a phone call and was told that "they decided to move forward with another candidate."

The question about well-ordered numbers: Print out all well-ordered numbers of length 'n'. A well-formed number is a number where each subsequent digit is greater than the previous, like 123 or 3569.
